From how far 3PO's legs are spread, I'm going to guess what we're seeing is the Coin one that was repacked in OTC. As for R2, he doesn't have a chrome dome, but looks pretty normal, so perhaps he's the Naboo/OTC version? I wish it were a plain R2-D2 with the R4-G9 body, but they really don't seem to want to give us that for some reason.
