So am I the only one excited... *trailer spoilers*
the possible return of The Arbiter and getting back into looking into the whole alliance thing? Really hoping Thel will play a big part in Halo 5. I didn't think I'd be that excited until I found he was talking to that new character, Locke. I guess I just felt like Halo4 almost treated him and the alliance like they didn't exist at all. So its good to go back to explore that. It was also quite clever how they used the trailer and his narration to tie in H2A with H5.
