No 3rd party developer is stupid enough to have a game exclusive to 1 platform. This goes especially for already established franchises. Have you see how Bioshock and Mass Effect sell? The sales don't match the hype and reviews.

Gears of War
Left 4 Dead
Mass Effect
Alan Wake
BattleBlock Theater
Trials Evolution
Minecraft

Etc, etc. 

Microsoft pays thme money to make it worth it.

All those games would have been much more popular/profitable if made multi-platform. Minecraft for example would sell very well on Nintendo consoles.
