It should so be named the Wii Beater. It would make it so much more ironic when it also only gets shovelware.
OT:
I don't think that they are talking about a Valve port. It is very possible that they just outsource the porting part to someone else, like they have done before. Not that it matters, anyone who has a 5 year old PC owes it to themselves to play it on the PC anywho.
