Well so far for me I guess 2007.
Metroid Prime 3 , Zack and Wiki, Mario Galaxy, Super Paper Mario, RE 4: Wii Edition
2008 runner up with Smash Brothers, No More Heroes and Mario Kart. 2008 was a very good year still and 2007 only edged it by a little bit thanks to Mario Galaxy.
2009 is better then the launch year anyways, but has awhile to go to match even 2008
It's just that simple.
