Though a bit hard to find, this post on the Halo Waypoint forums offers the latest update on Halo: CE PC.
The team is currently working towards having the first Halo: CE PC flight to Rings 1 and 2 by the end of this month with the goal of expanding to Ring 3 in February. For those who are wondering, “What are these rings you are talking about? Do we need to locate the Ark to join these flights?” No, you are safe from the Great Journey with this test. These Rings are different external groups we work with to help validate the builds we are wanting to flight and help us isolate critical issues prior to expanding to large scale flighting. A full breakdown of Flighting Rings and can be found in this previous Flighting Update from last year
