After years of speculation, Ars Technica is calling it "official": Apple is going to open an iTunes Video Store. Their proof? Graphics ripped from the bowels of iTunes 5 which include "Buy Video," "Gift Video," and "Add Video" buttons. Though I personally prefer to wait for the press release before throwing around a word like "official,", it does look pretty convincing. It remains to be seen, however, what kind of video they'll be selling. Movies? Concert videos? TV episodes? The Star Wars Holiday Special?
