The Return of Halo 5 Ranked System?

I noticed in the live stream today, they compared the marine difficulty bots to Silver ranked players and the ODST bots to Gold players. Could this be a sign of Halo 5’s Rank system making a return? Not sure if anyone else caught this.

Bot levels are Recruit (Bronze), Marine (Silver), ODST (Gold) and Spartan (Platinum).

Considering Bronze, Silver, Gold, Platinum, Onyx has been the preferred competitive rank system since Reach, I think it will probably make a return.

I just hope the seasons are a bit longer than a single month this time. That’s seriously way too short for anyone with a remotely busy schedule and other games to play. 3 month cycles are perfect.
