While HBO debuted the first Westworld Season 2 trailer at San Diego Comic-Con last week, the network also revealed that the new season wouldn't debut until 2018, although no specific time frame was given. During the TCA Summer Tour, HBO narrowed it down a bit more for fans, revealing that the new season will debut in Spring 2018. It's possible that HBO may be using the same Sunday 10 PM spring slot it typically used for Game of Thrones, before that show was pushed into the summer months. While we still don't have an exact date, at least we have a better idea of when to expect the season.

The Westworld Season 2 premiere news was revealed in a press release sent out by HBO during the TCA summer tour, outlining the cable network's immense slate for the rest of this year, next year and beyond. The Westworld portion of this announcement confirms that production on Westworld Season 2 is already under way, although no story details were given. Here's the Westworld portion of HBO's announcement below, which includes all of the Season 1 cast members.

Television; based on the film written by Michael Crichton. The Emmy-nominated series is currently in production for its second season, debuting in spring 2018."

While the Season 2 cast has yet to be confirmed, the show's presence at Comic-Con 2017 ultimately confirmed some of the cast members that are coming back. Stars such as Ben Barnes (Logan), Ingrid Bolso Berdal (Armistice), Ed Harris (Man in Black), Luke Hemsworth (Stubbs), James Marsden (Teddy), Thandie Newton (Maeve), Simon Quarterman (Lee Sizemore), Rodrigo Santoro (Hector), Angela Sarafyan (Clementine), Jimmi Simpson (William), Tessa Thompson (Charlotte), Evan Rachel Wood (Dolores), Shannon Woodward (Elsie) and Jeffrey Wright (Bernard/Arnold) were on hand for the show's Saturday afternoon panel in Hall H, with the trailer showcasing Jeffrey Wright, Evan Rachel Wood, James Marsden, Thandie Newton and more.

HBO renewed Westworld for Season 2 back in November, with series creators Jonathan Nolan and Lisa Joy revealing that the production delay for the first season actually helped the creators map out the first five seasons of the show. Still, while the stories may be mapped out far in advance, the production schedule is certainly a demanding one, and HBO is giving the show the time it needs to meet and/or exceed the high production standards the show already set during the first season. It remains unclear when we may see the next footage from Westworld Season 2, but with production still under way, we could get another trailer any day now.
