Mario Kart, Mario Tennis, Mario Golf, and Animal Crossing are all obvious future network multiplayer games. I can't believe they haven't even been hinted at, and I think that is a shame. I suppose Nintendo may be trying to avoid conflict with the DS titles. However I think they would be better off fully marrying the two systems. Eight player Mario kart with each of the eight players playing either local to a Wii or networked using either another Wii or a DS is an awesome idea. Only speculation, but the potential is there.
