Just wondering if someone could clarify this to me. When WZOR leaked Windows 8.1 on August 26, 2013 they called it as "RTM" (Release to Manufacturing). Later the same build released on 9/9/2013 on MSDN / Technet as Official RTM / MSDN Release. Now WZOR calling 10/17/2013 release as GA Rollup "A'. So can we expect something like Roll-up "A", "B", "C" and so on in later days?
