Microsoft has not officially said it's working on a Surface 2 tablet, so there is no official launch date. But reports hint that Microsoft's big Surface 2 unveiling will align with the official release of Windows 8.1 to consumers on Oct. 17. That's when Surface will be revealed with general availability by the holiday buying season. There is also a report, from NPD DisplaySearch, that the Surface 2 production volumes won't ramp up until the first quarter of 2014 to coincide with an official general availability date.
There also may be a revealment of the next-gen Surface capabilities as early as Sept. 26. That's when Nokia is expected to launch its "Vanquish" Windows 8.1 tablet at a New York press event, according to reports from Windows Phone Central.
