[UPDATE] HBO has announced Westworld Season 2.

　　The original story is below.

　　A second season of HBO's sci-fi/western Westworld hasn't been announced, but that doesn't mean the show's producers aren't thinking about what's coming next.

　　Creator Jonathan Nolan told Entertainment Weekly that Season 2 will dive into things like how the park's robots--known as hosts--are constructed. We will also learn about how they are powered. Interestingly, Nolan also revealed that the hosts do not require oxygen to survive.

　　"Their construction and their power source is something we're really going to get into during Season 2," Nolan said. "So we'd like to keep that mysterious. They're closer to biological than they are to mechanical, but they don't suffer brain death the same way we do."

　　"They're largely indistinguishable from a human beings, but their brains don't require oxygen--which opens up interesting possibilities," Nolan went on to say. "Their brains are not as fragile as ours. On one hand, their cognition is controllable and malleable, but on a structural level they can't be killed in the same way you and I can. There are advantages and disadvantages to being a host. Season 2 we'll be exploring more the nuts and bolts of what they are--as the hosts themselves are trying to understand."

　　At the end of October, HBO programming president Casey Bloys said it's "looking really good" for Westworld to be renewed for a second season. However, HBO hasn't made it official yet.

　　As of that time, creators Nolan and Lisa Joy had yet to pitch him on their ideas for Season 2. We've heard before that they have five or six years worth of Westworld ideas mapped out.

　　There will be 10 episodes in all for Westworld's first season, meaning there are three more to come before Season 1 wraps up. Episode 7, which aired on November 13, contained a major twist concerning a prominent character--read this spoiler-filled post to learn more.
