I just stumbled across this:

Interplay is going to release Descent as a downloadable game for the Nintendo Wii, complete with wiimote+nunchuk control. There is no specific release date, just "2011." I would take that as a sign that this is potentially vaporware, but they just recently released MDK for Wii, so I'm thinking that this is legitimate:
