I go for 61-80m
Smart phones will eat into 3DS sales more than PSV.
People wont be buying the new brain age game for £30 when they can get something similar on their phone for 59p. So Nintendo will lose a lot of that market...
Which leaves core gamers which is what they're aiming for with MH/MGS/Resi etc. With that market the PSV will provide some very stiff competition.
I think they'll sell very close, 360-PS3 & GC-XBOX close!
