If you already own a bunch of Xbox 360 digital games, they’ll continue to be playable. You just won’t be able to purchase new games or DLC from an Xbox 360 console.

They stated that you will still be able to redownload games you’ve already purchased. You just won’t be able to make new purchases. It’s kind of weird that the original article left that part out considering it’s what most people would care about.
