"Apparently the Sony Ericsson XPERIA X2 will feature a 3.5" WVGA OLED (!) touchscreen display and an 8 megapixel auto focus camera as its two most major upgrades. The processor speed will also be upped and the RAM will be increased to 512 MB.

The Sony XPERIA X2 will run on Sony Ericsson-customized Windows Mobile 6.5 OS (which will probably be taken beyond the X-panels UI plug-in). The panels themselves will receive some new features too, including PS3 remote play. They will also come with Windows Mobile 7 support so an upgrade will be possible when the OS eventually becomes available.
Finally, Assisted GPS will also be present onboard and so will the VGA video recording of the original Sony Ericsson XPERIA X1."
