Hamish at Marathon's Story has recieved an interesting composite shot taken from the E3 demonstration trailer by Claude Errera. Figuring prominently in the wide shot are a number of interesting glyphs, similar to the one seen on the building in the E3 banner.

Indeed, it could be that we are looking at the mechanism which will take the place of Marathon's terminals in Halo... poor Hamish is going to be awfully busy when people start scrutinizing every last texture in the game. ;)
