Were not quite sure what to make of the video above, which could be a future Sony Ericsson mobile. While it is rumored this could be the X1 successor, the phone instead resembles more of a PSP (possibly the PSP phone?). This is something we haven’t yet seen from Sony; and it also lacks the keyboard we are seeing in the X1. We can also see the icon set that is similar to the Playstation/PSP, while no apparent use the ‘panels’ interface common the initial Xperia. Details are scarce, however I think it’s no secret the X1 will be just the first of many for the Xperia line.
My guess is this is simply a prototype, and that of an old rendition of the P5i or the X1. The PSP is getting older, and a PSP phone would be a great way to keep a dying gaming handset alive.
