Surface Laptop 3, Surface Pro 7 and Surface on ARM. What's in shop for Wednesday's Microsoft Surface show?

Evan Blass has published multiple device renderings, including a Surface Pro 7 that adds in a USB-C plug instead of a Mini DisplayPort, and 10th-gen Intel Core CPUs.

He also noted to an ARM CPU-powered surface that is smaller than the usual Pro set with some severely thin bezels and likely targeting Apple's iPad Pro straight.

Finally, there's a presumed third-generation Surface Laptop, with no fozzy Alcantara to be seen, just soft metal, USB-C ports and AMD hardware inside 13-and fresh 15-inch screens.

What we haven't seen pictures of is any rumored "Centaurus" dual screen surface, but there are still a few hours left before all is officially revealed at 10AM ET on October 2nd.

According to Andrew Hewitt, an analyst at Forrester research company, Microsoft's primary public for these latest appliances are company experts.

Before the case on Tuesday, he observed that Microsoft has invested strongly in productivity components, including Timeline, which allows you to return to where you left off on documents and websites, and Focus Assistant, which reduces distractions such as notifications. Hewitt said.

"There is a sense that Microsoft is trying to compete with Apple on the creative front, with new capabilities for picture and movie editing. But the other features are much more aligned with Microsoft's mission to empower employees to be productive."
