While Apple is rumoured to launch its new MacBook Pro 2016 models in June this year, Microsoft could be there to steal its limelight, with speculations indicating the Redmond giant may also announce its Surface Pro 5 and Surface Book 2 devices in June.

On top of their releases, the Microsoft Surface Pro 5 and Surface Book 2 are expected to arrive with the Windows 10 Redstone update. According to ZD Net, this next major Windows 10 update, also called Redstone 1, will be available to users by summer this year. The Redstone 1 update will be arriving as the “Windows 10 Anniversary Update.”

The Surface Pro 5 is speculated to deliver better battery performance than the Surface Pro 4, which is rigged with battery drainage problems, and feature a USB-Type C slot. Speculations indicate that it will be arriving with a rechargeable magnetic Surface Pen stylus.

The device is also expected to house a 13.3-inch screen that will carry support for 4K resolution.

Similarly, the Microsoft Surface Book 2 is expected to support 4K resolution on its 13.5-inch display, with the performance of the device tweaked for higher graphics support and battery performance improvements.

There are some contradictory speculations that both devices may arrive in 2017 with the Windows 10 Redstone 2 update. According to this camp, the 2017 software upgrade is expected to bring along a more refined user experience and several new features.

However, as of this writing, there is no official information available yet on the Surface Pro 5 and Surface Book 2 devices from Microsoft.

Meanwhile, Apple is expected to unleash the MacBook Pro 2016 models in June this year through its Worldwide Developers Conference 2016 event -- one with a 13-inch screen size and the other a 15-inch screen size. The same WWDC event could also see Apple release a 12-inch MacBook Air 2016 device.
