Well, we don't really know for sure what happens. We have our suspicions with a lot of things. And for instance, just because[spoiler]we know that Collinwood burns, that doesn't mean that the damage is beyond repair. Have you seen that cache of jewels and gold that Barnabas has stashed away?
[/spoiler]And as I've also said, if what I suspect happens at the end of the film really does happen, it would be a tremendous tease to leave things that way. I would love to see a sequel flesh out how things might play out from there. Though there's always the possibility that a sequel would take place at some point in the past. Say some sort of version of the 1897 storyline. There are actually all sorts of directions for a sequel to possibly go in...
