It depends how good it is.
Early on, capcom gave the impression of rather half-hearted interest in the wii, and if the led to them pumping out a mediocre game, which reviews far less well than RE4, I expect a lot of people wont bother.
If it's a game that stands up on its own merits, I'd have thought the fact RE4 was a good port, that used the wii-mote well, would encourage more people to pick it up.
