For that one week it's a tough call. It all comes down to whether Wii U will be flat or up yoy for that week I guess. If it's flat I can see Vita possibly just pipping it.
However given Mario Kart hasn't boosted hardware too much there and Smash will be out. Wii U could be on a lot more kids Xmas wish lists this year when they couldn't have it in May.
I'm gonna go with Vita though as if marketed right they've had a very strong year of releases and Digimon etc in early 2015 could just put it on a lot of Xmas wish lists too. Phantasy Star Nova also has a lot of hardware shifting potential. It certainly compares to God Eater 2.
