This is the promise that was also explicitly made beside the release of Halo 5:G. Not only do I think this is Halo 2, I think using the word “journey” may be directly referencing Halo 2.
This is the first of the games in which we hear this terminology, and there is even a level with using “Great Journey” as it’s own namesake. Just speculation, but what do you guys think?
H2A, HW2, and the Ridely Scott thing that we’re getting would be a great start to our journey.
Ironically, however, our journey began in 2013… Spartan Assault.
But the Arbiter began with Halo 2 
Undeniably confirmed!
2015 more than likely …
There is a rumor that all Halo games featuring chief will be remade and pushed out for xbox one. If that is the case, mind blown. What they could end up doing is combining the settings, maps and modes from all of those halos, while also allowing you to play those campaigns in order. Given that 3 had forge, should the rumor be true, forge could be coming to all of those mp maps. It is just a rumor, but man we could finally have all of those vehicles, hopefully they can bring back the falcon as well because I prefer that design over the hornet.
I am very excited for E3.
