Indy has been part of the theme parks almost as long as Star Tours, so not a major surprise here.
The Star Wars saga has places to go with or without Han Solo. I'm not sure anyone is clamoring for the adventures of really Old Indy or Indy Junior. It would be tough to accept anyone else playing Dr. Jones unless it's a prequel.
And I still want to know if they got the rights to Willow and THX 1138. ;)
