Microsoft watcher h0x0d unearthed the patent this morning, which shows a center-folding configuration, not unlike the ill-fated Microsoft Courier device of yesteryear.

As usual, be aware that patents don't always equal products. Companies frequently file prototypes and even ideas that will never emerge from the drafting table as a protectionary measure. However, given the raft of previous patents Microsoft has filed on this particular configuration, I'd say it's safe to say that the company is at least exploring a foldable cellular PC design for an upcoming handset or tablet. The patent was originally filed in 2015 and was made public just yesterday. Unlike the previous folding phone patents which largely focus on hinges, this one provides a solution for reducing the visual impact from a screen that is comprised of several separate displays.
