No. I wouldn't want a similar controller or control system to Wii for Resident Evil 5.
I'm happy with my PS3 controller and I wouldn't want to be hampered by a controller I'm not familiar with.
I wouldn't want Resident Evil 5 on Xbox360 either. The series started on PlayStation, and I wish it would have stayed on the brand forever. Even if that meant the Resident Evil remake were never made.
