I'm a little bit let down. My expectations were way too high. I didn't think they demonstrated that NSMBU had features that were truly new in the presentation. The Miiverse component to it was cool, and the touch screen manipulation was kind of cool, but I was expecting something much more. Maybe because I had alreayd heard about the squirrel suit...
I was expecting a Metroid, a Zelda, more info on Smash Bros, or some other new Nintendo IP that was geared toward the core. NintendoLand is kind of cool for parties like Wii Sports, but I don't know if I would buy it. My guess is it will be a pack-in title.
