Have you played the Wii yet? It is an amazing party console, there are lots of great ways to play it with a group of people and a 24 pack
. Also i expect a lot of new games will come out within the next year due to the shear number of consoles that have been sold. Developers know there is a huge market here and it just takes time to get good games out for the console. Porting doesn't work so well to the Wii because the game has to be designed around the control scheme to be really good.
