come on man. Vita wont end one fourth of the PSP sales and 3DS wont reach one half of the DS sales, and you are telling me you dont believe the handheld market is shrinking? 

ds was bought by non-gamersc and PSP had 1 million more support then Vita it had more support then Vita+3ds support combined

so you are telling me a section of the market that bought the DS isnt buying the 3DS, then go on saying that the market for handhelds isnt shrinking?
