I think this console is going to be the Sega Dreamcast of this era. Nintendo is being shunned and doubted by both its fans, third party support and investors. In responce to this Nintendo is actually giving its fans something amazing. A system that has impressive graphical capabilities, classic and new gameplay mechanics and both casual and hardcore titles. Just like the Dreamcast, it looks like Nintendo is going to have a flood of great games and is going to do very well in the begining. However, when its competition arrives with new hardware that is visually more impressive (lets face it we know its they're going to be more powerful...) and more inclined to what the so called "hardcore gamer" audience wants and is going to give Nintendo a run for its money just like the Playstation 2 did to the Dreamcast.
I do believe though that if the fans see the true potential that lies behind the Wii U, then it won't be left in the background watching its competetors gain success just like the Dreamcast was forced to do. The people need to learn to forgive. Sega wasn't forgived for its slaughter of the Genesis/Megadrive and the early cannabalization of the lackluster Saturn and so the fans missed out on the offering of the Dreamcasts great offerings. Nintendo is going to redeem itself only if the people can move on and accept the legacy of the Wii. Embrace its new path and we will be rewarded.
Yes, I am going to be purchasing a Nintendo Wii U on day one. And I will support it and encourage others to do so, because we will be missing out on a great system if we don't.
