This similar thread for the other two consoles had like 15 games each.
With Halo and (to a lesser extent) GT5 out this year I don't think wii will OWN 2010 as it did the previous years.
I still expect SMG2 and Zelda to outsell Halo or at least go close.
I don't think we will see a 20m selling wii game like MKwii, Wii Fit or (potentially) NSMBwii launched this year.
Still I'll be getting at least 3 of those titles.
