The photo on the left is what appears to be Sony Ericsson’s XPERIA X2, according to an anonymous tip over at Engadget. The WIndows key on the top left part of the keyboard is pretty much a giveaway that it will be running on Windows Mobile. 6.5 perhaps?

The keyboard also appears to have a better layout and the screen is not as stretchy or wide as it used to be on the SE XPERIA X1. No exact word on whether the photo shows a prototype or whatever, but it sure does look quite convincing.
