It wouldn't surprise me if Wii U had already sold more than the Vita. We have so little real sales data for Vita outside of Japan.
Based on VGChartz without any further revisions I could see the Vita continuing to plod along in Japan for the next year or so. And Sony are very unlikely to replace it so there's nothing to kill the sales dead.
Wii U I see just falling off a cliff the second is successor is confirmed. I think we now also know every game of note that will ever hit the Wii U and rumours of the major Wii U titles being ported to Wii U will likely dampen enthusiasm of anyone who was interested in Wii U and make them hold off until the successor.
Really has been a much closer race then anyone would have ever thought in those 2012 threads though hahah.
