If the issue of whether the Skate would be 800MHz or 1GHz wasn't enough for you, Atomix86 asked about 1.4GHz dual core devices.
ZTE can confirm that it is devloping a device based on the Qualcomm MSM8255T. That Snapdragon S2 chipset has a documented theorhetical clock speed of 1.4GHz. (It is not dual core though.)
ZTE aims to have a device based on that Snapdragon chipset on the market before the end of 2011.
