Microsoft has the Surface Pen, Huawei has their own Pen, HP has their pen, but no Windows device has had a pen that works across all devices.
Along with its Windows Ink platform, Microsoft’s Bryan Roper has also announced that Microsoft is developing a pen in conjunction with Wacom that works with the a lot of pen-enabled devices.
Forgot something big! We are working with Wacom to create a pen that will work across a huge number of pen enabled devices!!!! #Build2016

With the Windows Ink platform , it makes sense for Microsoft to double down on the pen capabilities of their device, and what better way to do so than to make a universal pen.
