I doubt it. Wii U only outsells Vita during the holidays and it has maybe two good holidays left to make up over 2 million, probably not going to happen. The only thing that could change things is if Vita gets discontinued way before the Wii U does.
Besides if there's one console that has a more pathetic release schedule than Vita it's the Wii U by a country mile.
