According to MCV, there will be interconnectivity between the extremely popular handheld gaming system, & the newly released console that's currently taking the gaming world by storm. This is no rumor, either, apparently coming from Nintendo's DS product manager, James Honeywell. Makes complete sense to me...

"The link-up between Wii and DS will be much more about offering new forms of gameplay, fun and interaction. It will offer yet another new set of experiences for the whole family."
