Hack exist only some month after the launch of PSP so i don't the lack of game in the middle of it's life was because of hack and i don't believe psp was a success because of piracy or because of emulators and homebrew.
I don't know why developper abondon psp when many game sold well like GTA and the first Tekken on psp,games start to sell bad after third party abondon it.
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
