If this comes true, and I don't think it will, it will be a very slight victory. Personally I think you've massively overinflated the likely LTD sales of the WiiU and 3DS and to be perfectly honest, given the crazy USA FW for PS4 and the fact that struggling though it may be, Vita is currently a decent amount ahead of WiiU and will have a the typical long sony shelf-life, I think the most likely candidate for this gen overall is still Sony - nintendo can still do it, but it would mean refinding the casual audience that fuelled the Wii/DS boom and I din't think they can do it mainly because that sort of audience seems reluctant to buy the same thing twice (this is the main reason I don't expect Kinect 2.0 to drive many Xbone sales - the people who want that sort of experience already have it on 360 and have no reason to uprgrade).
When all is said and done, I think 3DS will hit around 90-100m, with WiiU at 15m for 120m total, whereas I see PS4 at 110-120m and vita and maybe 20m for 140m, and Xbone at about 50m
