Microsoft is preparing for one of its most critical Windows updates in its history, the Windows 10 release that will be available as a free download to consumers who already own genuine Windows 7 and Windows 8 copies. Beginning on July 29th, the update will be rolled out gradually, with Windows 10 retail boxes supposed to reach retailers at some point after that. But Microsoft is also working on new hardware for Windows 10, and a report already shares some exciting details for the next-gen Surface tablet.

Likely to be called Surface Pro 4, the next Windows flagship is supposedly launching this October. At least that’s what sources from the supply chain told Taiwanese tech news site Digitimes.

The Surface Pro 4 will feature “the same ultra-thin form factor, bezel size and large-size display as the predecessor model,” the website says.

However, the new Surface tablet will feature Intel’s new Skylake processor, and might pack Samsung SSD drives of up to 256GB. Other details have not been provided yet, and it’s not known how much the new Surface Pro 4 will cost.

According to the sources, the new Surface might help Microsoft increase monthly tablet shipments to 500,000-600,000 units from the current 300,000 monthly units.

Microsoft confirmed a few days ago that it plans to unveil new Windows 10 hardware at the upcoming IFA 2015 show in Berlin, Germany, without specifying anything about mobile devices. However, the company has an event titled Windows 10 Lights up New Devices for September 4th at the German trade show.

The new Surface Pro model – if it’s going to be unveiled in September – won’t be the only new tablet/laptop running Windows 10 out of the box. According to the company, “a breadth of new Windows 10 devices, including tablets, 2-in-1s, premium notebooks, gaming devices and all-in-ones” are about to be unveiled.
