I agree. COnsidering that some of the greatest killer apps are coming next year (and, being Nintendo and all, there will be bundles) I would suggest waiting.
Unless, of course, one can not wait to play 3d World, which is not a bad choice. Hell, it is problably a better reason to buy a console than any next-gen launch title so far.
So if Nintendo games are you thing, go get a Wii U guilty free, otherwise, hold your breath a little longer.
