Another Xperia X2 rumor surfaces

One of our favorite rumors that keeps going and going but never really getting anywhere is the Sony Ericsson Xperia X2. The follow-up to the Great Experiment known as the X1 has been seen in fits and starts, but there's still nothing really concrete to go on.

But in this shot obtained by Engadget, we do see a Windows Flag key in the top left of the keyboard. So, that means there's a Windows Flag at the top left of the keyboard. Whether this is a prototype of an upcoming devices or something since scuttled is anyone's guess.
