That means there's a decent chance this You're right, I just dug through the old thread and that was the case. .19 was CU, .15 was a full upgrade.
As its pushed to the slow ring what are the odds for some official ISO's to be released soon? Might this be "the one"?
It sounds to me that some believe that 17115 could be chosen as RTM, that is not gonna happend. This build has a watermark and timebomb, it will not be patched away. And i doubt it's gonna be another .15 build since they have a lot of numbers to chose on now compared to the FCU final build.
