A few new Sony Xperia model numbers were certified in China via CCC a few days ago. This includes model number M51w, expected to be the Chinese Xperia Z1 mini and the L39u, another Xperia Z1 variant for the Chinese market possibly for China Unicom given the WCDMA band support.
Another model number is XM50h, which could be a large mid-ranger, perhaps a 6-inch model running a Mediatek chipset. Rumours point to this model having the codename “Tianchi”. We may hear more about these products at CES 2014 tomorrow.
