Chopper.
Banshee(already confirmed).
Ghost.
They should also bring back the Spectre from Halo 2. I heard rumors of the Halo 2 Heretic Elites being in Halo 4. I would LOVE this.
Finally somebody who is doing something about it. I can't stand these kind of people I've made about 30 to 40 posts telling them to GTFO and go to an anti-halo website instead of bitching about what they don't like about it on here.
One can hope. I mean, there's always something you missed in the previous game. They could discover that the shield planet is infested with the flood deep inside another library like in Halo 2. The shield world kind of reminds me of High Charity.
I really don't think this would be good in matchmaking. I say this because it would pretty much be no challenge for the team with the Buffalo. No challenge = No fun.
Most likely not true, as Halo 2's online server was shut down due to a new system being released. Unless a new Xbox is released, I don't think we have anything to worry about. But if it does happen, I'll break my foot off in someone's ass.
