If you boot up your PS3 today you'll find a shiny new app waiting for you -- HBO Go. It allows you to watch a host of HBO shows provided that you have a cable subscription, including True Detective -- which you should get to watching as soon as possible.
Sadly, there's still no word on a PlayStation 4 launch for the app nor are there any updates for the Xbox One. Sony notes that they are working "diligently" though, so that's something.
Go watch True Detective while you wait.
