Since the Surface Pro 3 is one of the successful products of Microsoft, users are eagerly waiting for the Surface Pro 4 release date. Expected to be announced in October, the Surface Pro 4 is likely to be launched with improved specs over its predecessor model.

According to Digitimes, the Surface Pro 4 is speculated to be available in two display variants of 12 inches and 14 inches. Both the variants are pegged to carry support for 2,160 x 1,440 pixels resolution.

As far as the design of the Surface Pro 4 is concerned, the official Surface blog stated that the accessories of the Surface Pro 3, such as Type Covers and docking station, will be supported by the next-generation Surface Pro tablet.

The Surface Pro 4 is expected to be powered by the next-generation Skylake processors. Intel has already unleashed its Skylake Y, U, H and S processors at the ongoing IFA 2015 tech event.

The new chip that will power the Surface Pro 4 will be more power efficient than the current chipsets of Surface Pro 3. The Skylake chip is also speculated to be available in Core i3, Core i5, and Core i7 processor variants.

The stylus that will accompany with the Surface Pro 4 is expected to be more intuitive and touch-sensitive than the stylus of the Surface Pro 3. The enhanced text recognition feature of the Windows 10 will allow users to make the most of the new stylus on Surface Pro 4.

The upcoming tablet-laptop hybrid from Microsoft is also pegged to feature a larger battery unit. Along with the power efficient Skylake chip, the battery of the Surface Pro 4 will also deliver a better battery life than what Surface Pro 3 offers.

Tech Times claimed that the launch price of the 12-inch Surface Pro 4 will be $800. The 14-inch model is expected to be $100 or $150 costlier. A report from The Verge said that Microsoft will unveil the new Lumia flagships, the Band 2 smartwatch and the Surface Pro 4 in October. Speculations suggest that the launch event will be held on Oct. 19.
