^^ do you actually believe them?
by looking at the two games: World at War and Quantum of Solace, It's clear that the "scaling" process to the Wii started after Modern Warfare and not before. Treyarc did a lot better on World at War because they started working on the game when Modern Warfare was well into development (but left the game with no online gameplay). This is why Quantum of Solace looks pretty bad on Wii.
Any game engine is "scalable", any developer can tell you that. But it's the games that show if they tell the truth. The Engine of wii is far from finished
