I dont think so.
Mario Galaxy is one more lacklusting title from Nintendo, a company lost in it's own strategy : I ll do gamers games just because I heard they want some. What can I do ? Well, I'll take Mario G. and copy paste it in M.G.2.
End of the story.
You forgot Metroid M. Same story, no words on it...
Lack of 3rd party "big" annoucement make me fear 2010 will be the worst year either, and 2011 will be the death of the Wii...
