Although the article is purely speculative, it is interesting to note that the iPad's "Videos.app" could easily be replaced by the Apple TV's touchscreen-friendly interface.

Also: "So, one more sidetrack: If video is moved off of iTunes, the App Store is a marketplace for apps, and our books are bought in iBooks, could this mean that iTunes could return, gracefully, to serve its original purpose? Could iTunes just be for music? I just blew my mind."

Unfortunately, this seems extremely unlikely.
