Most of the good games played now were games that were delayed last year. And most of the good games next year will be games that were supposed to be released this year. So its like this image of games constantly never happening on time even though the X86 architecture is supposed to make games come to consoles easier. I think that is a big point of the argument.
But a large chunk of the comments seem to agree that the good games this generation are on Wii U.
