"Microsoft's Windows division is busy wrapping up the Anniversary Update (aka 'Redstone 1') for Mobile and shipping for PC, but the hardware division is hard at work as well. I'm now starting to hear reports of refreshed Surface devices being developed that won't radically change the current design but do offer some modest modifications.
Surface Book - Please mind the gap
First up is Surface Book, which sounds like is getting Intel's new Kaby Lake processor. Kaby Lake won't start shipping until late 2016, and it brings native support for USB 3.1 (Gen 2) along with a new graphics architecture for 3D and 4K graphics. While I have not heard Kaby Lake specifically name-dropped I do hear of 'updated internals,' which jives with earlier rumors of a SoC refresh for the Surface line.
Perhaps the bigger news is a fix for something that bugged some Surface Book owners: the gap in the hinge. The space allocated for Microsoft's unique fulcrum hinge, bothered some owners on aesthetic grounds (concerns over dust collecting in that area or structural weakness though seem to be unfounded). The alleged redesign I hear makes the display and keyboard flush when closed similar to a traditional laptop.
How the Surface team managed the change while keeping the dynamic-fulcrum hinge's functionality is currently not known."
