Sony just slashed ¥10k off the price of the PSP Go in Japan (effective starting Tuesday). That brings the price down to ¥16,800 or right around $200 -- a price point Sony has been toying with in the US for awhile. A quick search online shows a $199 listing on Amazon and Gamestop while Sony's US PlayStation store still has it listed at $249.99. That'll likely change any minute now.PSP Go price cut to $200 in Japan originally appeared on Engadget on Mon, 25 O
