Your link didn't offer up much good as far as HBO itself is concerned. But I learned that Amazon Prime plays host to a huge select of HBO's back catalog, and now know about this Sling TV service Dish is hosting, which might work out well for being able to catch some of the basic cable channels I'll otherwise miss after cutting the cord.
If HBO goes a little too a'la carte, that won't be too big a deal for me, since I currently only watch Game of Thrones and True Detective on there. So long as they're not outrageously priced (like $20 a month individually), I'll just subscribe to them, and get the rest of my movies and old TV shows through the other packages. All things considered, I should be cutting the cost of TV by a third without missing out on much at all.
Right now it's Game of Thrones and Homeland that I'd like to keep up with.
