At this point in time with all that has been announced we have:
IG-88
Probe Droids
R2-D2 and by association R2 units
C-3PO and by association 3PO units
2-1B Droid Hero
HK Assassin Droids.
What else can we expect to see? I figure that at some point once Rebels content is added to the game we will get Chopper and by association C-1P droids, but what else? What are the chances do you think that we will gain scum faction R5, R4, or GNK droids to the game?
The R5 and R4 droids could be a cheap unit that could boost the ability to cycle through your command deck as R2 is in skirmish, or even be used to increase the difficulty of Strength, Perception, or Tech checks in the campaign. Heck R5, R4, and GNK droids could potentially be used as a sort of portable cover, which I think would open them up to quite a few possibilities for both players of the campaign and skirmish game.
