Why would it go up?
Next month will be even worse. There is no way the Wii U sales will go up until software releases and no software (an original game with limited demographic appeal, a limited demographic port from the 3DS, and a late port of a racing game) will be released in March.
Shit's gonna be fucked for a while!
Yeah, February will be bad. March and April should be pretty good (100K+, at least).
The obvious reason for the poor January sales and the impending poor February sales is that there is no additional incentive to buy Wii U past what launch offered. Very few games were released, and none of them were high impact. February's catalyst was supposed to be Rayman Legends. I'm looking at Monster Hunter to be a good driving force for March/April.
