I dont think Capcom is really all that interested in the Wii or its WiiMote. Granted they can see a game-starved demographic when its in their face, but I doubt they'll devote resources to the Wii ports.
I think a lot of this has to do with the idea that in order to develop for the Wii full steam they need to take a big step back technologically, and commit to it. Unfortunately, along with profit, there is more to gain technologically by developing for the hi-tech competition.
Which begs the question why Capcom, traditionally a staunch defender of the underdog, has decided not to really go all-in with the Wii while it still supports the PSP whole-heartedly. What isnt the Wii giving Capcom that it needs? Flexibility? That'd be my guess.
