Apparently no source confirmed but it looks like they really are leaked photos of a supposed X10 partly disassembled.
“This bunch of parts pictured above is not the Xperia X10 you are looking for – assuming that you want one that works, that is. But, you will not hold of one before Feb ’10, as per the recent reports.
Do not worry, right now we have got something for you. Sony Ericsson Xperia X10 tear down photos. Guys over Mydrivers got hold of these from the FCC tear down inspection, which Xperia X10 passed recently.
To remind you, It’s specifications are a huge 4-inch capacitive touch display, 480×854 pixels wide. A 8.1 megapixel camera with LED flash. A 1GHz Snapdragon CPU. An 8 GB microSD memory card included, with the possibility of extending that with larger memory cards.”
