New details about Microsoft's next-gen Surface Pro series tablet have surfaced and they hint that the upcoming model might not be a significant upgrade over the current one.

The Surface Pro 5 could use the same power connector like the Pro 4 model, claims Windows watcher Paul Thurrott. Microsoft would use Intel's seventh-generation Kaby Lake processors, he adds.

Earlier report suggested that the processor would draw less power and it would result in delivering longer battery life.

Thurrott further says there won't be any dramatic change in the tablet.

Other rumoured hardware features are 4K display, Nvidia Pascal or AMD Polaris graphics unit for better viewing, artwork and gaming experience, microSD card slot for storage expansion and fingerprint scanner.

However, the Surface Pro 5 and Surface Book 2 might not come until spring 2017. Same is the case with Microsoft's long rumoured Surface phone.

Last month ZDNet reported Microsoft was planning to hold a hardware launch event in spring, where it might not unveil the Surface Book 2. It's unclear if the Pro 5 tablet would debut at the event.

While the question remains that what new hardware Microsoft would announce at its spring 2017 event, DigiTimes claims the company was working on a new 13.5in Surface Book laptop featuring a clamshell design instead of traditional 2-in-1 form factor, that would cost around $1,000.
