If you've been dying to get back into The Clone Wars, iTunes may be the way to go, at least for "Senate Murders." The fifteenth episode of TCW Season 2 is, as of this writing, available early on iTunes for the regular TV show price of $1.99. The reason for its availability ahead of TV broadcast remains a mystery, although it may be connected to today's U.K. premiere of the episode. Either way, Clone Wars fans are counting their blessings this morning because of a little gift, intentional or not, from Lucasfilm.
You can download The Clone Wars: Senate Murders here (warning: link opens in iTunes).
UPDATE: I'm told by the ForceCast's Jimmy Mac that the episode, while still present in the iTunes Store, reports a "No Longer Available" message upon attempts to purchase it.
