Sony Ericsson X2 Spotted?

A tipster tells us that the device you're looking at here is Sony Ericsson's codename "Vulcan" -- better known as the X2 -- which would presumably replace the X1 at some point in the next few days, weeks, months, or years. Though the picture's small, you can clearly make out the X Panel button in the lower left of the phone's front and a Windows key in the upper left of the keyboard, which adds a dose of credibility -- the company has, after all, put quite a bit of time and effort into pimping its panel interface SDK, and right now, the X1 is the only device that supports it. The image looks a little rough around the edges, but we can easily chalk that up to this being either a composite mockup or a very early prototype combined with the fact that our tipster seems to have blanked out the surroundings to protect the source. We're not saying it's definitely real, but this certainly looks plausible -- we're just not convinced yet that it looks better than the model it'd replace. Thoughts?
