This comes from Capcom's Takeuchi:
1UP: What about Sony's motion control device?
JT: Well just being from Capcom, I can tell you that we have a lot of good ideas on how to make use of that technology and we're looking forward to putting them into practice. However, speaking to other developers in Japan, I've heard a few of them say they were delighted by the Sony motion controller because they can just port over their Wii titles to the PS3.

So er, yes, I guess we will.
Also it amazes me they're porting No More Heroes to the PS3 and not Muramasa... that games clearly suits it more :/.
