"I Prefer Warm Halo, Sauted in Awesomesauce"
I was thinking of what bungie aerospace could be, and it hit me that it could be the beginning website of a bungie ARG.
I don't know if this has already been proposed (did some searching and did not find any) but it would fit with it.
When bungie day comes around, it will become clear. Can't you just see it, bungie day come and they unveil an ARG that leads to their next project.
Please correct me if there are any problems in my theory.
