Disney has really upped its game with programming on the XD channel and we're starting to see a lot of new geek friendly material popping up in the news.
The Tron: Uprising series mixes 2D and 3D animation and starts where the Tron: Legacy movie leaves off. It features some heavy weight voice talent as well including Bruce Boxleitner reappearing as Tron, Elijah Wood voicing the main character and Lance Henriksen stepping in as the bad guy.
On top of this they're playing plenty of super hero cartoons like Ultimate Spiderman and The Avengers. Sadly they seem to have cancelled showing the Stitch! Anime series but never fear you can order it from Amazon.
