So, way back in the heady days before Wave 7, this thread was my attempt to predict the future. After my inspired performance at the time (one out of four aint bad, right?), I'm taking another crack for the (presumably) upcoming Wave 9 announcement in a month or two.
I'm assuming a 5 ship wave, one per faction, if only because the new factions just don't have enough ships out there yet for FFG to start doubling up with them and getting them up to speed with the older three factions the way they did scum.
Rebel:
What We'll Get: Incom X4 Gunship
Why will we get it?
This was the hardest to pick, because the Rebels have got just exactly the wrong number of ships in the lore for a game like this. They have enough to provide generations of authors and video game designers to provide a wide variety of ship types without having to make up new ones (unlike the imps) but not enough to sustain wave after wave of X Wing ships (unlike, say, Scum). Rogue One has a decent chance of fixing that, but for now, the X-4 seems like the best of a bad set of options.
The X-4 has a number of things going for it however. It's a large base, forward arc ship like the Shuttle or IG-2000 (which the rebels lack) which could potentially get an auxiliary arc, another thing they lack. And, of course, it comes from Galaxies, which someone at FFG clearly has some fond memories for,
Why might we not get it?
This is a super obscure ship, but it fills a presently empty rebel niche, and all the other likely possibilities for Rebels are almost as obscure, but replicate some existing ship. The T Wing and R-41 are just slightly worse A Wings and Z-95s, respectively, although the R-41 may eventually find a place as a cannon carrier (though that would probably largely crowd the B-Wing out of it's last remaining niche now that BTL-A4 Y Wings and IA X-Wings are becoming more common).
There are still one or two very cool rebel ships that probably deserve a spot in the game, like the Longprobe Y-Wing and Recon-X, but honestly, these are probably best dealt with via title cards or, at most, repaints in an Aces type pack. A new mini, while cool, would probably be seen as overkill.
Imperial:
What We'll Get: TIE Aggressor
Why will we get it?
TLTs have, as we all know, had a huge impact on the meta, and FFG clearly knew that they would – there's no reason to give you two in a K Wing Pack unless they expected you to put them on HWKs and Y-Wings. They were well aware that it was a good enough card that players were going to want to do that, and they will have been planning for the meta shifts associated with that. It's not unreasonable that FFG will want to give Imperial players something that can mount it, and there's really not a better option than the Aggressor in the lore for a TIE with a turret (with the possible exception of the Ep. 7 Special Forces TIE, see below).
Why might we not get it?
FFG may have made the conscious choice to keep turrets out of Imperial hands indefinitely; it certainly took them a long time to give the Imps a PWT ship. In that case, the Aggressor is probably out for the foreseeable future. The gunboat then becomes a real possibility, filling the niche that the TIE Bomber and TIE punisher have so far more or less failed to fill, but that would be the first non-TIE small based imperial ship, and they might also have made a decision to avoid that. In that case, there are still options – the TIE Scout, the TIE Avenger, one or two others from Galaxies and the like, but none are quite as interesting as the Aggressor, meta wise.
Scum:
What We'll Get: Scurrg H-6 Bomber
Why will we get it?
Scum lacks a heavy bomber, and this is one of the best contenders in the Lore. In addition, FFG have used it in Armada, and we know the cross pollination between the two games is huge.
Could be quite a cool little beast for scum, and seems very K Wing like, with a turret slot, a crew slot or two and plenty of bombs, maybe even a salvaged astromech or, if you really want to stretch it, even two. Looks like there'd be enough pilots too, Lok Revenant Pirate as one generic, maybe Feeorin Mercenary as another, then Jinkins and Nym and your named pilots, and a Havoc title card.
Why might we not get it?
Scum are pretty much the most wide open faction at the moment, and there are tonnes of potential options, especially if FFG made the decision not to give them a heavy bomber in Wave 7 for a specific reason (although it seems more likely they just wanted to get the bounty hunters out).
As above, we know they love cribbing from Star Wars Galaxies, and there are still ships on the table there, like the Krayt and Dunelizard, as well as the AEG-77 Vigo, although all of these seem to take roles already served by existing scum ships, unlike the Scurrg. There's also the possibility that they might make book fans happy by going for something famous like the Skipray or Cloakshape, but again, these will compete with existing ships rather than bringing something new to the game. And then there's a whole bunch of other ships too – it's a big field that's hard to call. But the Scurrg is almost certainly coming eventually, and wave 9 seems as good a time as any.
First Order
What We'll Get: Special Forces TIE (TIE/sf)
Why will we get it?
It's one of the only FO ships that we know will be in Episode 7, and FFG have presumably been given access to it without any major spoiler issues (we know that LFL are keeping them in the dark as well about new movie details).
Also, the rear gunner gives FFG the option of either giving us something new in a small based ship with a rear arc (my personal preference) or an Imp/FO ship capable of taking a turret, which they're really starting to need in the TLT meta (see TIE Aggressor above). A crew slot is also a possibility.
Why might we not get it?
We've seen Kylo Ren's shuttle and some kind of landing craft – it's possible that both will end up in X Wing eventually, though they both have their own issues (Size in the case of the shuttle, and finding a niche for a landing craft in a dogfight game. It's likely that FFG will take the path of least resistance with the TIE/sf, but not quite 100% certain.
Resistance:
What We'll Get: No Idea. One of these maybe?
Simply not enough information has been released about what (if any) ships the resistance are using in TFA other than the T-70. Odds are we'll be able to make a better guess in a week or so.
Any other Possibilities?
It's possible that Wave 9 might be Resistance and First Order only, to try and bump up those factions, but that seems unlikely, given that we're likely only to have a very small selection of ships until at least 2017. FFG will likely want to drip-feed them and rely on the Rebel/Resistance and Imp/FO to give new faction players enough ships to stay viable, but it's possible that there's a plethora of new Episode VII content that Disney and LFL have been keeping from us, and that we'll see announced in the days after the movie comes out - the fact that they originally drew concept art for ships other than the new X Wing might point in that direction... but I doubt it. I feel like there would have been something - leaked set photos, Lego sets, Chinese factory leaks - something - if there were new ships that had been hidden so far.
Also, I'm on the record as saying that I fully expect prequel ships eventually - but not in this wave. That seems like something that will need another starter set, and given that the Ep. VII one just came out, a third starter seems way unlikely. Maybe for wave 12 or something.
Finally, it's possible that FFG will delay Wave 9 for ages and release Aces boxes or Epic ships in the meantime, holding out for Rogue One for new ships to populate the next wave. Scum does need an epic, and that announcement may be coming soon (Surely it must be the Action VI and Wild Karrde almost beyond a doubt). But, again, this seems unlikely - while Aces boxes make them money, I expect that new waves do too, and that is their ultimate goal, in the end.
Anyway, those are my predictions. What are yours? Let's do some crystal ball gazing! 
and a, 
slot, and makes
