Last week, a filing at the Bluetooth Special Interest Group site revealed the name of a forthcoming keyboard accessory from Microsoft. Dubbed 'Surface Ergonomic Keyboard' the device received a qualification assessment by SIG on September 25. The keyboard is thought to be a next-generation version of Microsoft's previous Designer Bluetooth Desktop kit announced in March 2015, which includes a minimalist Bluetooth keyboard and mouse.

We obtained through sourcing a new Microsoft promo image where you can see the new gray colored keyboard that presumably matches the magnesium coloring of the Surface series. The keyboard layout is also slightly different from the existing Designer Bluetooth Desktop kit suggesting this is not just a coloring change.

An announcement for the Surface-branded keyboards could come as early as this week, but definitely this month we are told. Update: Some more information has been added to this article including confirmation of a second, ergonomic Surface-branded keyboard and Mouse.

We've previously revealed that Microsoft was considering various sizes for the AIO, but new information suggests they have settled on the 27-inch variant for the market (likely with a 4K display). Numerous sources have confirmed with us that there is also a good chance that a patent filing earlier this year by Microsoft (spotted by MSPU) does reveal the near final design of the device, seen below.
