Sony Ericsson UK has a pre-registration site for the XPERIA X10 that states the expected launch date for the device as February 10th. Obviously that's in no way, shape, or form the exact date but it does give us a barometer to control our expectations. The XPERIA X10 is the device we are looking most forward to in the new year and we're hopeful that it can challenge the Motorola DROID as the best Android handset available.
Remember: 1GHz Snapdragon Processor, 4-inch touchscreen, 8.1 megapixel camera and that beautiful 'Rachael' UI. Just lovely stuff.
