I see what you're getting at, I could see how someone might assume an seamless outer space based on that. As soon as you realize how much of a technical undertaking that is though, it's easy to assume they wouldn't go that route and not have blown that horn 2+ years ago as a huge feature. Something like that combined with a BGS RPG would be massive and I can't imagine a world where a company like BGS or Microsoft would be wanting to keep that a secret until release.
