The C-3PO paired with R2, while not vac-metallic like the upcoming 400%er, looks to be more gold than the initial version from the Early Bird set. In fact, it looks identical to the ROTJ Deluxe series C-3PO with Salacious Crumb, except for the pulled-out eye.
I always thought the Early Bird Threepio color/tint was too yellowy/gray, drab gold, and not orange enough, if that makes sense. Though I'd love a vac-metallic 100% C-3PO (and an R2 with vac-metal shiny silver dome, for that matter), this is enough of a difference for me to get him.
Heck, I'm still looking for the Scout Trooper that came with the Speeder Bike, even though his only difference from the regular series 7 version is dirty feet.
