Well, we know that 3rd parties have the development kits for online, and now we’re starting to get developer confirmations.  This one is from Activision:

Activision’s newly acquired Demonware team recently spoke about online Wii plans. CEO Dylan Collins stated: “If you look at our track record, we’ve always been pretty much the first network guys on any platform coming out.” And when pressed further about if Activision has online Wii plans, he simply said: “Yeah, I would say we do.”

Ok, now we know they ARE working on games.  Now, PLEASE show something about these games.  Thank you.
