Do you think they will make Star wars parts 7-9?

It has long been rumored that Lucas could very well do it even though he has always said the complete story is told with parts 1-6. I would have liked to have seen more parts to the story but now with Hamil, Fisher and ford now pretty old, they would probably have to get new actors to play the iconic roles or Luke, Leia and Solo and it would seem wrong to see anyone else playing those roles. If they were going to make parts 7-9 than they needed to get cracking right after part six in 82.
