"Though six Halo ringworlds still remain largely intact, their current status and threat level is unknown."
Final sentence of the
Halo Waypoint video on the Halo Array.
Just thought that was interesting. They definitely seem to be building up to an announcement with these weekly videos. Last week's "The Covenant" ended with "The current state of the species which once served the Covenant remains unknown" followed by the Half-Jaw/Arbiter scene of "I would like to see our own world..."
The week before that? A summary of Cortana, ending with: "Both the Master Chief and Cortana have now found themselves stranded in an unknown portion of the galaxy with no apparent way back home."
I don't think they're building up to a Halo: CE announcement. Feels more like Halo 4.
Unless E3 gives us a Halo: CE expansion using Reach's engine to come out in November while we also get a Halo 4 trailer with a release date in 2012 or 2013.
