With a little more than a month from the official commercial release of Microsoft Windows 10, Microsoft is preparing to announce its Surface Pro 4 flagship tablet. Past release dates for Microsoft Surface products have been rather scattered, spanning across all four yearly quarters. Having said that, everyone is expecting the release of Windows 10 as the motivator for a possible August announcement of the tablet PC, alongside the upcoming release in the 3rd quarter of the Apple iPad Air 3, a product in near-direct competition with Microsoft Surface.
