While I think Nintendo has tons of great stuff they haven't talked about (Animal Crossing F-Zero etc.) I don't think holiday 2008 will have anything huge we haven't heard about. Thsoe games might get announced for end of year 08 but will land in 09. For this year expect a new color and a big push for WiiMusic, WiiFit etc. Kart will probably be teh holiday title, at least in Europe.
Final* Word on Game Delays:
The game will not be any better or include more content then planned. Any commnets that say so are just PR hogwash to make you feel better for having to wait.
Delays are due to lack of proper resources, skill, or adequate planning by the developer.
Do be thankful that they have enough respect for you to delay the game and maintain its intended level of quality.
