10.5.1 Rev.2 or 10.5.2 Rev.1 or 10.5.2 Rev.2 / Clarification

[megaargon1]

I know it is peak time, but will we be expecting Rev. 2 any time soon? I just want some clarification. Will the update be called 10.5.1 Rev.2 or 10.5.2 Rev.1 or 10.5.2 Rev.2? I would like to know before I download the wrong torrent. Thanks.
