This might be the leaked product shot of ZTE Grand S. It has a 5-inch screen that might have 1080p playback. Nothing is for sure right now. I think CES2013 will be the answer to most leaks recently.
Actually, ZTE has been leaking information on Weibo about the Grand S. It has a nice sketch of it and also showing a yacht that seems to be moving forward with the word Grand S.
Watch out for this handset during CES 2013.
