Not sure how to take these rumours about Han... other than with the usual large packet of salt! According to this older item of news he stipulated a character arc for Han beyond Episode VII... as well as one last Indy film. Either all that's changed or this recent rumour is just all BS:

"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."

...or Ford had a change of heart once JJ abandoned the original story treatment...
