Sony has made a brand new filing with the Federal Communications Commission (FCC) under a mysterious moniker - 'PSP-3001'.
As per usual with FCC filings, details are sparse and mired in confidentiality. What we can say is that the FCC was focussing its testing on the 2.4GHz spectrum for the PSP-3001's use of the 802.11b spectrum. In other words - Wi-Fi.
The diagrams (which demonstrate the location of the FCC label) display absolutely no difference between the 3001 and the Slim and Lite. That said, it's worth noting that the name for the Slim and Lite was 'PSP-2001', which makes the name 'PSP-3001' rather suggestive of something at least incrementally... different.
It was rumoured recently that a new model of the PSP dubbed 'PSP-3000' was on the way†
. This was supposedly going to feature a mic and a PS button in place of the home button. Neither of these rumoured differences appear in the diagram on the FCC's website.
So, basically, we know that the model does something different that relates to Wi-Fi. It could be a tiny alteration that relates to different components being used in the PSP's guts, it could be something big and awesome. Maybe a touch screen...†Source: Endgadget
