We already heard about a possible upcoming Sony Ericsson Xperia X2 launch late last year from Sony Ericsson but so far, nothing is confirmed. Nevertheless, Engadget Mobile just received a photo of a device which is said to be Sony Ericsson's next Xperia. Sure, at the moment it's just a rumor and also we haven't heard about the specs but the device seems to feature an arc-slider as well and clearly sports a Windows flag which is an indication that the next Xperia will also feature Windows Mobile (version yet unknown). Furthermore it sports an Xpanel hardware key which indicates that Sony Ericsson will continue its Xpanel GUI.
Sony Ericsson Xperia X2のリーク画像がでていますが、左上のキーボードのところにWinマークな印刷がされていることから、X2はWMなのではないかという噂があるようです(^^;
