I think alot of people will like the multiplayer part even if its just playing a 3d boardgame, being able to visual chat on the tablet with other wii friends. Won't you still be able to use the older controllers for like dancing. The graphics on the wii u will be alot better i asume, 1080p. I think the tablet for a visual aspect will be more pleasing for a glance just like how the wii mote had the extra sound coming from it. Its also one of those things that are meant more for kids, teenagers and families, I think.
