This confuses me. Isn't this essentially how it already works? Like QuickTime is how you play video files and you can organize videos in QT just like you can do so with music in iTunes. I know both apps are kind of tied together, but it seems like outside of Podcasts they already have two apps doing two different things. Does this also mean they are killing QuickTime?
