There is so much potential for DS and Wii interaction =D especially with them both being wireless. A message addon for the DS might be nice... so that the DS has DS messages like the wii has wii messages. Then they can message each other. It would just be another card for the DS and then an update in the wii message software =) Basically email software for the DS lol.
That's all I can think of right now! But there are soo many ideas!
