I know the game looks great, but let's not go crazy.
Seriously, it's kind of crazy to want TWO versions of the same game, even if it's on different console. I mean, PS3, X-box and PC are probably going to be the same.
And from what sources say, Wii, PS2, and DS are going to be different. DS especially, but I'm not really going to be buying every version for the sake of having it.
Just my opinion though. You are free to do whatever you want.
