PSP Go, the latest iteration of Sony's portable console, won't be going for much longer.

According to what appears to be a blog run by a Sony Store employee, Sony is discontinuing shipments of the handheld. Similarly, Sony's Japanese online store says that the device is out of stock.

A representative from Sony did not address the question of whether the PSP Go was being discontinued. It is a very exciting time for PlayStation portable devices. Before the end of the year we are launching NGP, our next generation portable device, which we believe will revolutionize portable gaming, the representative told Kotaku. In the meantime, the current generation of PSPs continue to be in demand, especially since the introduction of our value for money, Essentials range of games and we will continue to meet that demand.

Sony announced the PSP Go during the summer of 2009 and released later that year. The device, which lacks the UMD drive featured in previous versions of the PSP, only supports games via digital distribution. While Sony passionately advocated the feature, consumers did not share the company's enthusiasm.

Sony is already working on a successor to the PSP, dubbed Next Generation Portable.
