HBO plus more. Same price. Only details I gleaned so far were Southpark, Ric& Morty, 10,000 hrs of old content from Time Warner, and 50 new HBO Max shows by 2021. Also seem to remember reruns of Friends or something being a part of this. in 2021 they will add an ad-supported version to the mix. So the proposition to HBO customers today is for no money extra you can get a lot more content.
