I love it.
When an "exclusive" DOESN'T go multiplatform, everyone starts saying "well, I guess they dont want to make any money". But when a game does go multiplatform, everyone says "lawl, Sony lost another series!"
Why don't you just come out and say it - You're pissed the game isn't going multiplatform because you want to play it and dont own the proper system for it. Because that's what it all boils down to.
Any game that goes multiplatform will sell better than if it's an exclusive. Imagine Halo being released for the PS2. It would have sold MILLIONS more copies. But hey, I guess MS & Bungie don't want to make any money.
