Re: Han’s line, if we are to go by the new canon, he lived the first twenty years of his life in the slums on Corellia. Unless I’ve missed something, it doesn’t seem like any battles during the Clone Wars were fought on that planet, so it’s entirely possible and very likely that he never saw a Jedi. He didn’t leave until ten years after the purge, so it’s doubtful in his travels around the galaxy he would have seen a Jedi (until Obi-wan, of course).
Regardless, it’s too good a line to get rid of.
