Well, we are immediately raising hands to answer that. It looks like a smartphone, and it's probably the Sony Ericsson Arc HD aka Nozomi, judging by the boxy top end, if we compare it to the leaked photos of Sony Ericsson's first dual-core smartphone.
a 12MP rear camera, and an HD 720p display. Better late than never to the party, we'd say for SE's first dual-core handset, and we are dying to test what could turn out to be a mighty rear camera at CES 2012.
One of the comments under the photo says "It could be a sandwich...", and Android ICS should be indeed present on the handset, nestling under the Timescape UX interface overlay. Oh, the biggest mystery left is the actual name the device is going to take upon unveiling, so stay tuned for our coverage of CES 2012.
