Interesting thought on the Star Wars Universe

This is nothing about nothing, but where’s it written in the rule-book that the Lucasfilm gravy-train has to wrap itself up into a tight little ball and retire at six films?

My guess: Episode III gives way to Star Wars: Intermission (which is nothing but a black screen set to a John Williams score), followed by Star Wars: The Part You Missed When You Were Taking A Leak.
