This is stirring again and I really would like an all white droid like is in that pic Nick posted... Thinking about other colors, again I think the mix/match potential on Protocol Droids is limited. That said, I think the solid color diversity would be a nice addition and maybe they'll make some cool colors. I'd like a black 3PO unit, some RA heads maybe. I can't see them going balls out with droid diversity but who knows I guess.
That early pic Yakface showed is pretty cool IMO... maybe some are never gonna be happy but to me it's some SA droids. I'm cool with that.
