On: New Windows 10 Devices From Microsoft

Next year there will be a Surface Pro 5 (5"), Pro 8 (8") and Pro 12 (12") all with pens. 12 will be the successor to current Surface Pro 4.

They already have Surface (10.8") and Surface Pro (12"), so I don't see that changing.

There was speculation of a Surface Phone, but with the Lumia 950XL being pen compatible and still keeping the Lumia name, it's very unlikely.
