Lucas is a creative guy, and surrounded by 100's of creative people he pays $1,000,000's of dollars in payroll to, so why won't they give us Star Wars 7?
1)The Dark side of the force is gone from the universe, but now that the Empire has fractured,it has no central leadership, so this give the regional governor's an opportunity to power grab territory using what's left of the Imperial fleet.
2) Luke's the only Jedi and is now burdened with the responsibility to revive the Jedi order-find worthy recruits.
3)Han and Leia get married. Han has to still deal with his past and Leia now has to consider her 'destiny' regarding the force.
4)The Rebellion has the difficult task of soliciting the scattered systems throughout the galaxy to re-form the Galactic Senate.
5)Boba Fett has illegitimate children who want revenge on Skywalker-maybe one discovers his armor and weaponry,asks mom,"what's this?'", and swears to avenge the death of his father he never knew.
6) Piracy and organized crime spread due to the power void left by the Empires defeat, adding to Luke's problem- maybe Lado and Chewy can handle this scenario. Etc.,Etc.
So you see, the Star Wars universe is RIPE for new adventures, new stories, new worlds, new drama, new wars, new characters for a new generation.
NO EXCUSES LUCAS!!! GIVE US A NEW STAR WARS!!!!!!!!!!!!!!!!!!!!!
