I just preordered today for the $20 credit, but I see that the PS3 version and 360 version use different art. I preordered for PS3 since the overkill version is supposed to have a lot more content. Hope we can all get the overkill edition, I would think they are all overkill editions being first runs of the game, similar to Medal of Honor and other EA titles.
I contacted an EA forums mod who said the first run of titles are the Overkill Edition so I would suspect we should all be okay regardless of what platform we choose. Amazon hasn't responded however. I'm sticking with the PS3 version.
