Microsoft is holding its annual Build conference in San Francisco this year, promising to place the focus squarely on developers. With a Windows 8.1 preview planned for the same day, and the promise of some Xbox One development news, it looks like Microsoft might be ready to explain how all of its key products will work in harmony together in the future. With rumors of a new Surface announcement, and a focus on 7- and 8-inch devices with Windows 8.1, there could be an additional hardware focus at Build alongside the key software aspects. Windows, Windows Phone, Azure, Internet Explorer, Office, Xbox, and Visual Studio will all make an appearance at the event and we'll be there live to cover it all.

Sean Hollister and Tom Warren will be on the ground at the Moscone Center, live blogging the whole event as it unfolds. It all begins at 9AM PT / 12PM ET on June 26th, so don't miss it!
