The tablet was released with Windows 8.1, but was eligible for an upgrade to Windows 10, and towards the end of its sales life, it came with the newer version of the OS pre-installed.
Rumors have suggested that the company is also preparing a product unveiling, though the existing leaks and speculations are very unlikely to generate excitement among Microsoft fans.
Microsoft is all set to unveil a new product at an event slated to happen in China today.
Microsoft's Panos Panay may have just the let the cat out of the bag. What we're checking out here aren't regular $130 Type Cover sequels, but rather fresh, diverse takes on the Pro 4's single $160 Signature Type Cover model. While the Surface Pro family of devices have been especially fine ultrabook replacement devices (with some exceptions) from the Surface Pro 3 onwards, the Surface Family has seemingly outgrown the need for a designated "Pro" device.
The Surface Pen could contain a small rechargeable battery which is topped up whenever the stylus is sitting on the edge of the Surface Pro 5, held in place by a magnetic connector.
Surface Pro 5 up next? Microsoft teases cover keyboards
As you can see there would seem to be four new Surface Pro keyboard accessories launching and they appear to be in similar colors to the Surface Laptop options that were launched earlier in the month. Although the tech giant remains tight-lipped about the highly anticipated Microsoft Surface Phone, but reports are claiming that Microsoft is building three versions of the smartphone aiming at business and corporate users. At one point there were strong rumours to suggest Microsoft would channel its Surface laptop 2-in-1 technology into a powerful phone. We haven't heard much more on the subject since those images surfaced.
Microsoft said: "On May 23 in Shanghai, Microsoft will show the world what's next".
Of course, until Microsoft officially reveal whatever it's planning on 23 May, we can only speculate.
