the Wii mostly targeted casual gamers, but the Wii U will target both casual and hardcore gamers
the controller looks like a traditional controller but has a big touch screen, almost like a tablet
it is said to be 50% more powerful than the PS3, but the power is likely to get over taken by the next PlayStation and Xbox, and showcased games of current generation
it will not be capable of playing DVD or Blu-Rays, but is backwards compatible with Wii games
the console itself looks like the Xbox 360 and Wii had a child
Finally, Zelda, Mario, Metroid and Super Smash Bros. all in HD!
A: The Wii U? more like Pee Yew!
B: lol, epic fail
What separates this from other video game consoles the unique controller: the Wii U Gamepad. This controller has a 6" touch-screen built into it for unique/new ways to play video games. Surprisingly, it also is very comfortable. It does not use motion controls at all.
While the Wii U is more powerful than the 7th generation's video game consoles, it is not as powerful as the PS4 and Xbox One (Which is why Nintendo decides not to directly compete with them). Also, while the Xbox One and PS4 use X68, PC-like processors, the Wii U doesn't, making it harder to code games for both the Wii U and any other 8th-generation console.
Lastly, the Wii U is Nintendo's first console capable of 1080p gaming. Also, the Wii U is backwards-compatible with the Wii's games.
The Wii U is Nintendo's first HD console.
Guy: "Why the hell would I buy that iPad piece of dead crap when the PS4 killed it already? Get a real next gen console you loser."
Wii was a one-hit wonder with enticing motion controls, everyone has that now. A generation behind in its time, you knew the PS4 was over 5 years away. But PS4 is just a year or two past Wii U, everyone will wait instead. Casuals will stick to their original Wii and ipads/pods.
The most important fact is that it takes time to get to know the hardware of a game system well, for the developer API's to get to that point where they can make great looking games. Wii U is only 50% stronger than a PS3, but modern PS3 games look over 50% better than 1st gen PS3 games, so the result is when Wii U is released, its games just aren't going to look much better than PS3 games. Nintendo could have used this opportunity to be the first to market a serious next-gen contender and re-dominated this gen like they did the last one with Wii, but intense feelings of guilt of how much insane money they made with DS and Wii's success has caused them to want to destroy themselves with Wii U and the overpriced 3DS. When Microsoft and Sony release their next-gen systems that are going to have better frame rates, handle 1080p 3d games, better texture resolution, anisotropic filtering, physics, other nice graphics effects, Nintendo's corporate harakiri will be complete.
