Hello, for all Wii owners that expect so much for this game; you can ask directly to the developer Infinity War what features you want in the game for Wii.
This is the link:
I ask Infinity War for the use of WiiSpeak, Co-op and the DLC directly to the SD card on Wii. You can do the same.
Come-on Wii owners push for a better COD: MW2 on Wii!!
