From what we've seen, no.
Wii party U looks to have even less apeal then Nintendo land, and wii fit U currently is just wii fit but you can use the gamepad as a screen.
A lot of people have compared it to the 3DS and I think its fair, the casual audience need something new to grab them. The fitness and brain training fads are dying, I actually think Micorosoft is in the best position to win over the casuals with Kinect 2, which looks to amaze people based on the tech demos. The price tag is a problem but at least it not $599 lol
