What I am surprised about though, is many people saying the PSP doesnt have that many games good enough to buy the system. I just find that baffling.
I mean sure, the PSP's library isnt at DS level sadly, but it still has MANY great games from many genres.
As for the PSP Go lol, well, I think the sales numbers are pretty much expected, even for Sony. Most people still buy games from retails. The PSP Go is just a small push for the transition for digital distribution. It was never meant to be 'the next big thing', pretty much like how DS lite was for the DS fat.
