3ds is doing worse then ds becaue majority of casuals gamers are happy with their ds casuals don't really care about better graphics,Vita in other hand is doing worse then psp because psp has a lot better support then Vita,look at how many IP on psp didn't come on Vita
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
