For starters, Call of Duty's graphics aren't even that good to begin with. It's actually at least two years behind its major competitor, so no one I know plays it for graphics.

Next, with the Wii U coming this year, the Wii is already fading. I believe the last significant title for it (which was a Japanese Import) has already been released, and now everyone knows about the Wii's successor.

Either Treyarch is already developing a Wii U port (The Wii U, according to leaks, is scheduled to launch on November 18th, a mere 5 days after Black Ops II), or they're waiting until next year.
