The sixth version of the Surface Pro 2-in-1 tablet was supposed to finally include USB-C connectors, but an early unboxing unveiled that this may not be the case. The overall design appears to be almost unchanged, however, the hardware was upgraded with gen 8 Intel ULV CPUs and improved iGPUs. The official unveiling is scheduled for October 2.
