The sport is probably the most interesting out of all of those mentioned. There will always be a market for sports subscriptions, so they could have a very competitive offering there that Netflix aren't even involved in.

Marvel, Lucasfilm, etc. I'm still not seeing it. Two or three movies a year that I can pick up on DVD/Bluray cheaper. And that's if they're even worth buying on DVD after having watched them once in the cinema. Marvel movies have been wearing fairly thin, and Star Wars is showing similar fatigue.

I'm not saying they won't have a big market, Disney are huge afterall. I'm just saying that I really don't see them as strictly a direct Netflix killing competitor. They're in a slightly different game, content-wise, and Disney's biggest enemy will be itself.
