Train wreck on 14 January 2013
The ps3 had a couple 50k weeks early on, but that's with only two main territories (and the damn thing was $500+). The Wii U is achieving it; sooner and with one more main territory.
The Payroll tax increasing and debt hangovers from the holidays are not going to help any of these systems anytime soon, value is going to win out and that is where the Wii U and Vita are going to lose.
