Yesterday multiple outlets reported that the PSP Go was being discontinued. Today that rumor has been confirmed by Sony as the truth. Sony told Japanese website AV Watch that new PSP Go units would no longer be manufactured or shipped "in order to concentrate on the NGP." The remaining PSP Go stock will be sold until it's gone.
And what of the PSP-3000's fate? Sony told the web site that "it will continue to be sold," and that the company will keep focusing its attention on it from here on out.
The PSP Go went on sale in the fall of 2009, but was not well received by some. Last October, the system's price was slashed. Sony took a real gamble on eliminating UMD support in the new system. It has proven to be a gamble that they have lost.
