Wii U doing surprisingly well given the lack of releases and I suspect that will continue over the holidays - however the release schedule is bare and that will hurt it in the beginning of next year.
MK8 will of course be a popular game, question is is that just by Wii U standards? I expect respectable sales but it will fall short of even Double Dash on GC I think - the install base simply isn't there
Vita staying afloat, DW8+XL a little disappointing, but then it is a late port of a game that many will have on PS3, especially the hardcore musou fans who I would imagine make up most of the audience for the expansions. That said, though I don't have the figures on me, I suspect that is much lower than DW:NEXT, which is concerning
