My ideal would be three SAs side-by-side in the bubble on a normal Deluxe card.
The packaging on the Evolutions is overkill, especially for an army building set where 80% that are sold will be ripped open anyway -- carded collectors only need one, but openers will buy multiples. And it could shave a buck or two off the retail price.
Besides, these clone sets aren't truly Evolutions since it's three of the same type of trooper.
Part of me thinks that's the best option too... 3 SA's on a deluxe card with just the right gun (rifle, given that we have a ton of the carbine at this point). But the idea of the Evolutions styled box (not "Evolutions" figures though, just a reuse of that packaging style) would be ideal if you were getting MORE accessories... Just thinking outside the box on that a bit, but not expecting it. But I could see zip-lines, a rocket launcher, various weapons...
I agree that the Evolutions packaging would be overkill if you got nothing additional in there... I saw the EE Clones as overkill on the packaging too, being something you couldn't buy on sight, and for army building... Selling it in a store makes the packaging slightly more important. I'd be more than happy with 3 SA's on a Deluxe cardback though, but I'd be ecstatic for 3 SA's in an Evolutions styled box with a ton of different gear... Just doubt it happens that way... The one thing I know I certainly hope not to see is the Deluxe Clones reused and that's seemingly everyone's first thought, so I'm not too pumped on this line right now... Should be interesting to see in the coming weeks (and/or months) what is what.
