Disney Are So Very Close To Greenlighting "TRON 3"

This week see's the US and UK release of sci-fi sequel, "TRON: Legacy" which see's Jeff Bridges returning to the role of Flynn from the original film from the 80's. The film hasn't even been released yet, but Disney have already got writters plotting idea's down for a sequel which is under the working title of, "TRON: Revolutions".
So far various websites have been told that one of the idea's for the sequel see's Cillian Murphy's uncredited character from the sequel return in full and have a BIGGER role this time round if the 3rd film get's a deffo greenlight. But none of the idea's so far have Jeff Bridges returning, but they do have Bruce Boxleitner and Cindy Morgan's character return for the sequel. They don't appear in the second film, but may be back for number 3. I wonder if there's any chance that the writter's will bring back Flynn's son? They are considering bringing back Olivia Wilde's character.
I am heading off to see "TRON: Legacy" sometime next week, so I'll find out what the plans are for the 3rd film. Who will die in this film and who wont, ect......
