Spy shots reveal a Sony Ericsson Windows Phone 7 prototype

Sony Ericson is getting back in shape in increasingly larger leaps. Their Android lineup is getting more and more competitive and now it seems that Windows Phone 7 is in the cards. Some blurry spy shots reveal a Windows Phone 7 device with a full QWERTY keyboard.

Apart from the photos, there is really no further information. Could this be the XPERIA Pro 7? We can safely assume that this Windows Phone 7 device is running on at least a 1GHz processor of some sort and will offer 512MB RAM, at minimum. The display is surely over 3.5-inch and there is a full four-row QWERTY slide-out keyboard.

It is hard to say whether this is a real project or just some mockup but we cannot think of a reason for someone to go to all this trouble just to start a rumor. And it probably seems logical that Sony Ericsson will venture out in expanding its portfolio with a second smartphone OS.
