The reason why vita sold poorly it because a lot of psp series are not on vita.
Where is original mgs,original gta,tekken,socom,pes,original monster hunter ,original final fantasy etc
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
