Agreed with what has been said already...
The BB-8 set is a must-buy for BB-8, and like Jesse said, aliens are aliens (and they could be army builders too?). Zeb/Chopper is a must-buy for people like me who have never even seen a Chopper in the wild, so kudos to Hasbro for that set. I'll probably pick up Ahsoka and Vader for the novelty of having an animated Vader.
I WANT a 3PO/R2 set, but I mean I have the OT version already and managed to get that set with decent paint. Never saw a Rebels version with good paint, so we'll see, but I can't help but think a TFA 3PO would be one of the first figures in a SA line since we have some SA 3PO's already that they could easily repaint.
