OK. Sounds like the project that's "familiar" and breathing on us in our sleep is the next DLC mappack which includes Moonbase alpha , Purple Reign , and hopefully an as yet undisclosed map. The project that is speeding toward us is most likely an Arcade title (not entirely sold on the arcade maybe a different IP[ hopes]). and the third project with the hints from Lukems ( forward and prolouge ) is most likely a prequel to halo, ( possibly an ODST squad based game?). Lo means yet as in Yet there is still another. That's my opinion, take it or leave it.
