They will not release it on the Wii themselves if they feel that it will impact the quality of their work on the Xbox 360/PC/PS3 versions. If Infinity Ward don't like the Wii the are in a powerful enough position to not develop on the platform. Keeping the developer happy is better for Activision long term than even a few million sales on the Wii. Its quite likely that Treyarch will handle the port to the Wii.
Tease.
