Again, who really cares. The games will look great, and will be lots of fun, that's all that matters in the end. Nintendo is in the business of making money, at this point, the U is powerful enough to do what needs to be done. Maybe the PS460 will blow me out of the water, but if that's true I'll have to buy two consoles as usual. Nothing major.
It'll probs mean that the U will get more games custom for it (exclusives), and less multiplats. At this point we're used to it.
