Psp was a failure... it doesnt matter if it sold 75m os 150m, didnt sold sotfware at all it was a total failure. Look at 360, its 68.3m shipments but it already sold 650m games, probably 750m when this year ends. Thats a sucess.
I had 2 Psps, mine and from my brother and we bought 2 games.
Psp was a failure, didnt seold games and nobody cares about it.
Vita can be different, make it happen sony.
