Sony Japan has confirmed that production of the PSPgo has ceased, with a statement issued to Japanese site AV Watch.
The statement says that production has ceased in order to focus efforts on the forthcoming NGP, although PSP 3000 production will continue.
Sony has issued a statement which neither confirms or denies circulating rumours that production of the PSPgo has ceased, instead focusing on the prospects of the forthcoming NGP.
The original report surfaced in a blog, translated by Andriasang, which was apparently written by a Sony shop employee. That blog highlights the fact that the link to the PSPgo has been removed from the Sony Store website, although the product listing still exists on that page.
The UK's Sony site has the white model go in stock, but lists the black model as "temporarily unavailable".
Sony's statement in response to the stories is inconclusive at best.
"It is a very exciting time for PlayStation portable devices," Sony told sister site Eurogamer. "Before the end of the year we are launching NGP, our next generation portable device, which we believe will revolutionise portable gaming.
"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."
The download only portable has certainly been far from successful for Sony, rarely exceeding triple digit weekly sales figures even in Japan - where the PSP has seen such continued success.
Some retailers were unhappy about the model, too, excising them as it did from continued attached sales. Specialist Dutch retailer Nedgame, the country's largest, even refused to stock the device.
