The Surface Pen was pretty appreciated so far, as a pretty accurate pen with 4096 pressure points, rather comfy to use and supporting 21 ms latency, plus tilt. It even has a rubber eraser for wannabe artists and their corrections. Oddly enough, in spite of the $100 price tag, the device still used the old school AAAA battery.

A magnetic attachment to the device is also likely, especially since the previous Surface Pen could already be attached in that way to the Surface Pro 6.

Microsoft could also take the S Pen route and implement a supercapacitor here. Surface Pro 7 was recently leaked as starting from a basic Core i3, 4 GB RAM and 128 GB SSD config, going up to a Core i7, 16 GB RAM and 512 GB SSD.
