Will there be any connectivity between Wii and Nintendo DS?
Yes. Nintendo has not officially announced any kind of connectivity yet, but Shigeru Miyamoto told Kotaku in an interview that the functionality is built-into Wii, and it just has to be taken advantage of. According to Miyamoto, Nintendo is still coming up with ideas on how to use the functionality. One example Miyamoto referenced involved using the DS touch-screen and microphone in a Wii game. Meanwhile, another idea involves downloading content from your Wii to your DS, editing it, then uploading it back to your Wii. Nintendo doesnt know when this kind of connectivity will be available, but because of the DSs widespread success, it says it wants to have Wii and DS connectivity functionality available at launch or soon after.
