well here are some expected soon
Pokemon Ranch Channel - Owners of Pokemon Diamond and Pearl can upload their Pokemon to the Wii so that they may see and interact with them in 3D. You can also use you own Miis to play with the Pokemon. Even if you don't have Pokemon DS, you can still interact with the ranch and the Pokemon that litter it. Players can also take pictures and send them to friends.
Nintendo Channel for All - This new channel will let people view game trailers of upcoming Wii and DS games and download demos to the Nintendo DS. What's more, Wii owners can also see how many other users have purchased Wii titles and show everyone how much time people are playing each game based on the play history information stored in the Wii console. Nintendo aims to give consumers ways to find new games based on popularity and their own preferences. Nintendo will also collect this data for future use. This channel is also scheduled to launch in November in Japan.
Mii Contest Channel - Announced at E3, this channel will let you post your Miis for anyone to download. Nintendo will also administer themed contests, where users create, post, and vote on Miis. It is also set for a November launch in Japan.
Wii Fit Channel - Instead of being a download, the Wii Fit Channel will actually come with Wii Fit when it is released in Japan on December 1. The purpose of the channel is to make it easier for people to track their fitness progress without needed to swap out game discs every day, something that Nintendo says would make it troublesome to stick to losing weight or otherwise using the game to help stay healthy
