I will wait for More Games to be Announced Sony said all first party sony studio work on ps4 and Sony always take gamescom more seriously then Xbox so i think in the end PS4 will win.
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
