Basically the release time on Monday depends on the results of the QA team testing any last minute fixes the devs submit for things they noticed while watching streams over the weekend.
If there is something nasty they really want to get fixed before Public Experimental but the first attempt didn't work then they might need a second or third build and the release can push later into the day.
They had two different builds on the internal Testing_Trunk branch this evening per steamdb for example.
