The company didn't explicitly say this is about Surface, but the signs are clear. A teaser image shows a side-on look at what appears to be a Surface Pro. Microsoft usually holds a hardware-centric event in the fall. On top of that, the event takes place two weeks before Microsoft releases Windows 11, and what better way to showcase the latest OS than on shiny new hardware?

As for what to expect, we might see a refreshed Surface Duo. Recent leaks suggest the Surface Duo 2 will have an upgraded camera system and it may be available in black. The Surface Book lineup is due for an upgrade, and, given the teaser image, it won't be surprising if we learn what's next on the Surface Pro front. In any case, Engadget will cover all the big news out of the event.
