Microsoft has confirmed that the Windows 8 Release Preview will be out in the first week of June 2012.

Microsoft has been fairly open about Windows 8's progress, last week detailing the various versions of the OS; Windows 8, Windows 8 Pro and Windows RT. Windows RT is the edition that will run on ARM architecture.
What all versions of the system will feature is the freshly designed Metro interface, bringing the Windows 8 computers and tablets more in line with Microsoft's Windows Phone software.
