The chair seems to seriously imply that Han (and/or) Luke will die and that the original cast will play a small role, likely not returning after this film. The girl is your new Luke Skywalker, Stormtrooper guy is your new Han Solo, bonus X-Wing pilot for a love triangle and the old sidekicks shoehorned in, all seemingly modeled after vintage ESB bedsheets.
With midnight madness events launching product on September 4th, it's going to be very hard to avoid characters and story info. I hope this time we don't get a soundtrack with a title like "Qui-Gon's Noble End."
