The new Surface Pro X is here, and it is not called the Surface Pro X2. Instead, Microsoft continues to call its ARM Surface the Surface Pro X, primarily because it has only made iterative upgrades. The Surface Pro X is now available in Platinum with new Signature Keyboards and can be equipped with Microsoft's new SQ2 processor. No details have been offered about the SQ2, though.
