"Nintendo officially states that the following games will be coming out for Wii in Japan in 2007:
Donkey Kong Taru Jet Race (DK Jet or DK Bongo Blast, US) - June 28, 2007
Wii Health Pack -- 2007
Disaster: Day of Crisis - 2007
Mario Party 8 - 2007
Project H.A.M.M.E.R. - 2007
Wii Music - 2007
Super Mario Galaxy - 2007
Super Smash Bros. Brawl - 2007
Battalion Wars II - 2007
Forever Blue - 2007
Mario Strikers Charged - 2007
Metroid Prime 3: Corruption - 2007
Mario and Sonic at the Olympics - 2007"
Although this is only for Japan, many of these games seem like they would release in the US earlier, if not the same time as Japan.(i.e. Metroid Prime) Atleast, I'm hoping they will. Looks like there's a lot to look forward to this year.
