Microsoft has been steadily releasing Test Lab Guides for the various, upcoming Server-related R2 releases like Windows Server 2012 R2 and System Center 2012 R2 products. Those that have released over the past few months have all been brandished "Preview Release" as part of the title. The latest Test Lab Guide, released on Thursday, is the first one to have "Preview Release" removed as part of the name, which means that we're one step closer to the exciting, public unveiling on October 18, 2013.
