I don't see a "significant" graphical leap.

Can the Wii U play next gen titles? You decide.

yes

No. Not proven yet...Watch Dogs is not next gen and neither is Assassins Creed. The 720 and the PS4 are much, much more powerful. Thief and the Witcher 3 would be on the Wii U if they were next gen. 

Wii is aprox. 15x-20x less powerful than the 360 and PS3

Wii U is aprox. 5.5x-6x less powerful than the Xbox One and PS4

This doesn't mean the Wii U will get PS4 and Xbox One games, but it will be A LOT easier for devs to port their games. On Wii, devs had to make games from the ground up, this won't be the case for the Wii U.
