Well, if that's the case it wouldn't be a simple port - since the Wii's tech specs are less than those of the other consoles, then, assuming DMC4 pushed the PS3 hard, they'd need to cut it down greatly for it to work on a Wii.
"Beer is the mind killer. Beer is the little death that brings total obliteration. I will face my beer. I will permit it to pass over me and through me, and when it has gone past I will turn the inner eye to see its path. When the beer has gone there will be nothing. Only I will remain."
Make beer, not war.
