Yep...Wave 1 was Arcee, Starscream, and Bumblebee.
Cliffjumper is in the 1.5 wave (not sure who he is replacing - most likely Bumblebee since he was 4 to a case in Wave 1) and is popping up in Canada already, so we should be seeing him here in the States soonish. TRU and online stores (BBTS and HTS, for sure) are the ones carrying the First Edition figures.
The Robots in Disguise version, I think, is a new mold and is part of the non First-Edition lineup (which will see more saturated distribution)...and there's also a Terrorcon Cliffjumper coming out.
Awful lot of toys for a guy that had lasted one episode (not that I'm complaining - it's an awesome looking figure).
