If Infinity Ward really didn't like the Wii, they wouldn't have made the engine scaleable. They would have forced Treyarch to make another engine for WaW on the Wii or use the same engine for 3.
The fact is that if Call Of Duty 4 could have been on the Wii in 2007, it would have been. But the engine wasn't ready for it yet. It wasn't out of malice or dismissal of the Wii (unlike say , Resident Evil 5). It was that they just couldn't do it until now. IW didn't have the engine ready, and Treyarch needed to get used to the engine with WaW.
What about MW2? I don't know. Perhaps that will come next year as a dual release with the next Treyarch game. Or it could come as a dual release with the next IW game.
But Activision is not just throwing the Wii a great game later on. They are giving this game to the Wii when the finally can do so.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
Plus, just for the hell of it: Kelly Brook at the 2008 BAFTAs
