I find that youtube movie thoroughly unimpressive, the macroblocking and encoding quality make it a poor showcase, even if the original did not have those artifacts, it makes it impossible to judge the quality. Also, these kind of highly optimized tech-demos always paint a very rosy picture of what is possible, and are hardly ever realized in real games.
The leaked specs so far put the wii-u somewhat on par with the 360/ps3, which is nearly 6 year old hardware at this point, possibly 7 by the wii-u's release. Thinking that the wii-u will be able to match the next xbox/ps4 on performance is just hilariously naive
As for the motion controls and ms/sony not being able to match the wii-u on features. Given that we know jack-all about the new xbox and ps4, other than that they are comming at some point, MS and sony can not only feature match, but also outclass nintendo quite easily.
