I can't believe the number of people who say never, ps3 sold 80+ millions and ps4 sales are a lot better then ps3 in the same time frame and their is no sign of changing 3ds in other hand is tracked a lot worse then PSP this year in USA so even if possible it's not sure that 3DS will doing better then PSP.
I would say ps4 will outsell 3ds in 2018
PS4 - over 100 millions let's say 120m
Xbox One - 70m
Wii U - 25m
Vita - 15m if it will not get Final Fantasy Kingdoms Heart and Monster Hunter 20m otherwise
3DS - 80m
