Fresh rumors suggest that Microsoft Surface Pro 4 will be a major upgrade over the Surface Pro 3 from 2014. Even though Redmond-based technology giant has not revealed any official information about the device, latest rumors suggest that it will be unleashed on Oct. 4.

According to the recent tweets from Tom Warren, the senior editor with The Verge, the Surface Pro 4 will not be featuring Intel Core M chips and the device will be sporting a larger display. The forthcoming laplet is also expected to be thinner and lighter than the Surface Pro 3.

The Surface Pro 4 will appear different from its predecessor model. However, previous rumors suggested that the form factor of the Pro 4 will be very similar to that of the Surface Pro 3. The newer model is also expected to support the docking station of the SP3.

Warren claims that the Pro 4 will be an incremental upgrade over last year’s model, with rumors suggesting that it will be powered by the advanced Skylake chips. He has also tweeted that the Surface Pro 4 may not feature the latest USB Type-C connector. Instaed, the device may feature USB 3.0 and USB 3.1 ports.

Since Warren has mentioned “definitely wait for the 4. October” in one of his tweets, speculations are indicating the Surface Pro 4 may release on Oct. 4, according to Design & Trend. The device is also likely to come preinstalled with Windows 10.

Even though Warren has revealed a lot of information on the Surface Pro 4, he has not cited any a concrete source for his claims.

According to Yibada, the Microsoft Surface Pro 4 may come out in two display variants of 12 inches and 14 inches. Since the Skylake chip is highly power efficient, it will be able to deliver to longer battery backup than what the Surface Pro 3 is able to offer. The device will be available in RAM variants of up to 16 GB. The maximum storage that will available on the Surface Pro 4 will be 1 TB.
