This is what the title’s producer had to say about Devil May Cry 4 coming to the Wii.

You know, a lot of people ask us if we are going to bring out a Wii version. I simply don’t think you can make the game the type of game it is, with the awesome graphics and control — I don’t think that would work on the Wii. So, I don’t think we’re going to bring one out, no.
