The next generation of the Surface is already well underway with many expecting
it to arrive around the launch of Windows 8.1. With the Pro being the flagship of the Surface lineup, you would expect Microsoft to up the specs from the previous iteration and that’s exactly what they have done.
The Surface 2 will run Intel’s latest line of chips, a Haswell-based Core i5, Neowin has learned from several sources. In addition, the RAM will receive a considerable bump,
being doubled 4GB to 8GB. Finally, while
the device will look similar to the current Pro, Microsoft has
"refined" the kickstand that ships with the device. What the refinement is exactly, we don't have a clear picture yet; it could be a more robust stand that is stronger or one that offers alternative viewing angles, but this is speculation at this point.
Coming with the new Pro will
be another media campaign that will again try to raise awareness about the device. Now, we know a new media campaign will launch around the time of the Surface release, but we don’t know if Microsoft will stagger the release like they did with the RT/Pro (RT arrived in October and the Pro in February).
