I'm not ****ing stupid, I know what a skybox is! I said bungie referred to the skybubble as the skybox when they first told us about it, then they changed it to stop confusion!
And I'm saying that from everything we've been told, Forge World is the only map that goes out to embrace Forge, and the other maps are smaller and less forgeable to compensate for memory. It is HIGHLY unlikely that what was said means "a forgeable area above the map", because that doesn't fit in the quote (he WAS talking about the graphical skybox, I am 100% sure). That doesn't mean there won't be one, it just means that he wasn't talking about it there and so we have no evidence to even start thinking that there is one. I can just about guarantee you that this game is packed to the limit and Zealot won't include a skybubble forging area.
