Is it eight total, or eight main endings? If it's eight total, then that's pretty weak. If it's eight main endings like NCR, Legion, Independence and House (but four more), then it's pretty impressive, but I doubt Bethesda is capable of it. Wait since it's eight over two characters, then it's probably four a piece and they're just trying to make it sound better than it is.
How many total possible combinations of endings did New Vegas have? Like 29 slides with mix and match of multiple possibilities?
I dunno, I don't believe the article at all. Todd Howard said over 200 endings for Fallout 3 and that was just before the release (by a couple months).
