For next wave of releases.
Big ship speculation aside... how much is left for fighters? From around the Rebellion period
From my knowledge of Rebel fighters there are... T-Wings, M-Wings and H-wings left (otherwise they're minor variations on A-Wings, Y-Wings or X-wings)... and backgound on the T-Wing was that it was supposed to be a replacement for the A but wasn't as good.
For the Empire - the Starwing, Missile boat, (which wont gel well with the TIE series stuff), Scimitar Assault Bomber (combining "scimitar" and "bomber" could be confusing), TIE Agressor, TIE Vanguard (a tie with 1 attack dice and 1 shield?), TIE Hunter (TIE Interceptor with shields and missiles... so the TIE Defender?).
The ARC fighter? Some were still around after the clone wars period, could go to either side.
In short it seems they might soon have released the bulk of fighters that anyone cares about...
So where do they go once that happens?
Aces 2 for both sides? So Ace X-Wing and Y-Wing releases? Ace TIE Bomber and TIE Defender box?
Otherwise it's time to look at significantly different eras Perhaps Naboo fighters, Jedi Fighters, TIE Predators and Automated TIEs?
I think this is more interesting area for speculation than an Imperial huge ship (though I'd imagine there would be two - one about the size of the transport, and one big enough to put moving turrets on)... so what do other people will think will be released as starfighters in Wave 5? And how many waves are realistically left?
