I just placed my order at SWS.com for one of each Clone set - dirty and clean. That'll work just swell. No way in **** I need two of each. I think it'll work fine (with my OCD) to just have both poses of each Clone displayed with one clean pose and the alternate pose in dirty. Yes, that should be sufficient. I swear.
But I wouldn't be terribly surprised to see them pull another "Blackhole Stormtrooper" Bust-up type of deal with these, since that generated a pretty decent amount of hype for the line the last time the bastards did it...
