EDIT: Yeah, I got the numeral backwards...
The shiny new Scum faction is great and all, but this is also HWK Aces, Y-wing Aces and Firespray Aces all in a bundle together! (Z-95 just gets ported, poor thing) Trying to pick out what the present factions get in terms of new ship options in the new wave:
New Turrets! Offensive options for your HWK and Y-wing other than ICT!
Autoblaster Turret: Looks like a heavy weapon turret. If it's anything like the Autoblaster cannon then it's probably an anti-agility gun.
Astromechs!
But, um... no. Sorry.
If you look closely, the astromech icon is different! It's an R5 head rather than an R2. Looks like FFG have given Scum's Y-wings a different set of astromech upgrades. I guess that's because the Rebel ones lack Rebel Only. Sadly this locks the Rebels out of the new astromech droids.
Cannons!
Flechette Cannon. One guess what that does. The other one is "Magn..." Cannon.
Y-wing bombs!
Replaces a torpedo slot. Looks like it's nonunique too. Y-wings now have two ordnance slots, but any combination of Torpedo or Bomb. Bombs for the rebels and they get to take two. That indicates pretty strongly that one of the upgrades in there is a new bomb, as none of the old bombs are present.
New Firespray Title!
And it doesn't appear to be Scum only.
Auto(thrusters)?
The maneuverability upgrade that the Interceptor's apparently going to love from Starviper.
