I think Ford's concept is to let the world belong to the hosts (no longer the humans) & that people won't visit unless they want to risk death. That's why (to me anyway) the show will never be able to go back to where the first season began. *w/ the hosts being subservient. That isn't a bad thing either, just something to know going into season 2.

Couldn't agree more. Kind of exciting as to how many worlds might get discovered/revealed in season 2. Not to mention the 'what rules' attitude the hosts might start to live by in Westworld (some of them anyway).

I think there will be other worlds because of how Ford talked to Dolores at the end as well. The most intriguing element to me is what other hosts will be self aware w/ a conscious? We saw the group Zombie walking towards the board members & shoot MiB. We also saw the native not obey & capture (possibly kill) the guy looking for Elsie. To me those are bread crumbs leading to several other worlds, just a question of how many of them abide by the 'rules' & how many have evolved beyond them?
