I'd say it's going to last quite awhile, they're pretty explicit on their terms and I'm not sure why they would arbitrarily set this limit now only to move the goal post in the very near future. The tvOS seems to differ from iOS in that they are really pushing for cloud based storage for any and all persistent content. They want the minimum amount of logic required to be stored on device and most assets streamed. As far as video caching goes, it's not going to happen for 3rd party apps. Not sure if apple will bend the rules for their own apps.Sure, the limit is 200MB now. Let's see how long that lasts. It also makes a huge difference whether any video is cached on the storage.
