Good news, today RC3 was released, is supposed to be the last RC before RTM which is very promising.
If the news are right we are waiting for RTM in a month, I hope that this is a realistic estimation for the time needed.

Downloads are available, I’m in process of upgrading my lab from RC1 to RC3. For that purpose I will user clean install and restore a configuration backup. Upgrading is not of my preference, but will eventually try it later on.
