It's kind of meaningless to anybody except me, but I've had the gut feeling that the title will be something along the lines of The New Republic
We've had both the Sith and the Jedi (opposing forces and philosophies) in titles, two that are somewhat vague at first glance but represent negative and positive (Phantom, Hope) and - of course - Empire. The opposite of the Empire in goals and philosophy is, of course, the Republic, whether old or new.
I know, I know. That leaves Clones. There's always one loner that stands out from the rest.
You're probably more right than wrong. They follow a certain, yet vague, pattern.
The Phantom Menace = A New Hope
Empire Strikes Back = Attack of the Clones
Return of the Jedi = Revenge of the Sith
I remember some discussion around the original title of Return of the Jedi, and whether it should have been titled Revenge of the Jedi. The middle two movies share a theme of "striking back".
