Well-regarded Windows blogger Paul Thurrott and tech blog Neowin report that the software giant is working on a Surface Pro docking station, something The Verge has since corroborated by saying that the accessory will launch alongside the second-generation Surface Pro tablet later this year.
The dock apparently has arms at the side for locking or releasing the tablet, and will allow users to connect with keyboards and mice via USB (both USB 2.0 and 3.0 are supported), and to a bigger screen through mini DisplayPort or a wired Ethernet connection.
However, in a blow to Surface RT owners, the docking station will supposedly only work with the first and second-generation Surface Pro tablets.
Microsoft is also rumoured to be working on a Power Cover, another new accessory which is said to include a battery that charges the Surface Pro, Surface Pro 2 and Surface 2. The keyboard cover will not however work with the original Surface RT tablet because the original Surface tablets have different connectors.
Both the Power Cover and the Surface Pro docking station are expected to be released as Windows 8.1 goes live. The operating system update is due to launch on October 18.
There has been plenty of speculation over future Surface tablets in recent times, and even Microsoft is now failing to deny the existence of the new models.
The new Surface Pro and Surface tablets are expected to have a new kickstand, 8GB of RAM are will run Intel's Haswell processor and Nvidia's Tegra 4 chipset respectively, according to reports. Both tablets could also launch as Windows 8.1 starts shipping on October 18.
