Jon, I agree about feeling cheapened... Plus, they're droids we already have, and not exactly exciting color choices. Neither did much in the films, though to Q5's defense he'd be perfect for the Death Star obstacle course.
An R5 would be nice though... Still these appeal to me because they're something vastly different than we're used to, and at this point astromechs are tough to improve upon... You almost have to go the gimmick route, so I'm ok with them as is.
I still have to order these new ones if I want them... With how nice R2 is, I really want the set now, but an R5-D4 would be appreciated next time just because.
