The gap is currently at slightly over 700k consoles in favor of the Wii U. The PS4 did outsell Wii U troughout most of the year, but only by less than 500k. And with the holiday season favoring Wii U by quite some margin, I think the gap at year's end will be around 800k again. Unless Wii U stops selling the PS4 will need to strongly ramp up sales to get past that gap in 2016.
