Whatever it is, reports online are stating that Harrison Ford will reprise his iconic role for J.J. Abrams Star Wars sequels. According to the blog Jedi News, which is obviously clairvoyant:
A verbal agreement with Ford to play Han Solo once more has been in … place since before the Disney deal [for the Star Wars franchise]. Over the course of this summer financial settlements were reached. The outstanding points that had dragged on but are now resolved [is that] Ford wanted to see the synopsis for his character's development over more than just Episode 7. He saw this in August and is happy with the story arc.
That means they already have a storyline! And that Solo is in multiple episodes. Whoop! My guess is after the Battle of Endor, Leia dies, so Han heads back to Tatooine to take over Jabba the Hutt's mob empire. He becomes a grizzled space Mafia don and the new Jedi, retrained by Luke Skywalker, are sent to take him down.
Of note, Ford would only sign the deal if Disney agreed to make a fifth Indiana Jones. Maybe the new one won't completely blow?
