So I was just playing forge on Halo 4 on the map Outcast from the Castle map pack and realized how much the scenery and landscape in the distance from the map looks like what we saw in the Halo Xbox One Teaser.
The planet/area seems to consist of mainly deserts and sandy landscapes, there seem to be some angled mountains similar to those seen in the trailer and there is a huge planet within view of the map. I just thought it was a cool little theory that the two are linked.
What does everyone else think?
