But Microsoft is expected to unveil a new Surface All-In-One PC at the end of this month, so we're hoping to get confirmation of the peripherals at the same time.
This week Windows Central published a picture of a Bluetooth keyboard with a simple, two-tone grey design and room for a numeric keypad on the right side.

But the Surface name suggests they may be created to work with Surface-branded computers, like maybe an upcoming desktop.
The Surface Keyboard will be based on the Bluetooth 4.2 spec and require two AA batteries that are stored underneath, which Microsoft claims will last up to 12 months.
