If a game has yet to be announed don't expect it to come out this year. Nintendo is smart. No need to push the big Ip's till the Wii's popularity wanes.
A new Zelda? Forget it. I'd rather let them take the time to make a new Zelda game amzing anyway.
What about Punch out? I can't wait for that one. Too bad Mike Tyson won't be in it. I loved that game.
