Nope, nada. All I know is that it's at least a 20GB install on the 360. No idea whether it'll require the disc to be actively playing in the drive in order to work. I was just thinking that I really need to go mental and step up this thread by spamming it everywhere until I get a damn answer. Obviously, 20GB is 3 discs fully installed btw, but seeing as how W:TNO was 4 discs and Destiny looks fairly huge by comparison, there's a decent chance that it'll be more than 3 discs, which just raises my initial question/concern all over again.
