Huawei Ascend D2.
The specs on the device are still being guessed at, but will be released at CES 2013. At this point, speculation points to a quad-core 1.8GHz processor, most likely developed in house, 2GB of RAM, a 13MP camera and a 4000mAh battery. In other words, besides the larger screen, the Huawei Ascend Mate specs are what you would expect to see on a 2013 high-end phone.
An ad for the Huawei Ascend Mate also was leaked, making it clear that the Chinese manufacturer has been targeting Samsung with this device all along. The ad shows the outline of the 6.1 inch screen compared with the outline of a 5.5 inch screen. Hmm. Wonder what device that is supposed to be. Earlier this month, Huawei Senior Vice President Yu Chengdong told prospective buyers of the Samsung GALAXY Note II to wait for the launch of the Huawei Ascend Mate and he called Samsung's device "grossly overpriced."
