I don't think there are really any strong wii sports 2 rumors, but surely they will release SOMETHING which utilizes controls very weell.
Like I've said before I just flat don't see how they can do good this holiday season without a new zelda game. It's not at all because I am a zelda fan. I just am realistic enough to know that the only series which is loved by a wide audience type are zelda, mario, metroid, super smash brothers. That's it. To big time video game fans games like kid icarus and f-zero would be great, but for the type of audience that would go in masses toward holiday gaames it's got to be mario, zelda, metroid, or smash brothers. And considering zelda has had more time between it's wii launch than any of those others, I don't see how they can afford to NOT have a zelda game released. But honestly I don't expect it since Twilight Princess was announced several years before its release so it's not normal for Nintendo to announce a game and then release it the same year it was first announced unless it's not in one of the main few series.
