Sony made some big announcements today about streaming content on PlayStation systems. First up, HBO Now is coming to PlayStation 4 and PlayStation 3, Sony said in a blog post.

A specific release date for the HBO Now app was not announced, but it will be out before the October 2 launch of HBO's highly anticipated sci-fi western Westworld.

The other big piece of news today is that HBO and Cinemax are coming to PlayStation Vue, Sony's live TV streaming service. These will arrive before Westworld as well.

According to Sony, the launch of HBO and Cinemax for PlayStation Vue represents the first time live HBO programming and Cinemax content will be available without a bundle subscription. You can subscribe to HBO and Cinemax by themselves for $15/month each or you can add them to an existing Vue package.

"PlayStation has always been at the forefront of innovation and we are thrilled to build upon our partnership with them to meet the evolving demands of television audiences," HBO business developer head Jeff Dallesandro said in a statement.

Westworld is produced by Star Wars: The Force Awakens director JJ Abrams and Jonathan Nolan, who co-wrote several of brother Christopher's movies, including The Dark Knight Rises and Interstellar.

It's a re-imagining of the 1973 Michael Crichton movie of the same name, with a high-profile cast that includes Evan Rachel Wood, Anthony Hopkins, Ed Harris, James Marsden, and Jeffrey Wright. Nolan has stated that part of his inspiration for the show came from video games such as Red Dead Redemption and BioShock.

A new Westworld trailer was released this week--watch it here.
