Netflix will start streaming Disney content including its library of classics soon. This will also include the other non-disney branded films like National Treasure,
In 2016 they will be the premiere location for new movies after theatrical runs are through, before premium channels(HBO, Showtime, Starz, etc.)
The blog article did mention that they will be showing Disney
content so there may be a bit of hope left for TRON Uprising
My take is that Disney decided they didn't want to get in the paid streaming content business and Netflix presented a more profitable solution. Disney get's paid xxx hundred million dollars over 5-7 years and all they need to do is email links for Netflix IT to download high-quality film copies from their servers.
