"Now the Wii owners won't buy it because they feel betrayed"
Bull. Wanting an exclusive is a fanboy thing (not calling anyone that, just pointing out what that attitude it). Many of us just want some kickass FPS with good control, that we don't need a table/desk to use a keyboard and mouse to play. This will not change that, especially since it also has local multiplayer now.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
