Oh, it's clear they have no interest in changing the endings, though I haven't a clue as to why.

But like I said, that site isn't changing the endings, just elaborating on them. That, plus the general gist of the Weekes interview, is why I think it's a pretty fair guess as to what the Extended Cut will be like.
