Actually that would be quite cool...Sam Flynn takes over Encom, and he eventually thinks his crap don't stink. And furthermore he has millions of fanboys exquisitely sensitive to his Reality Distortion Field.
The Tron sequel idea I had would have had Kevin Flynn basically becoming a Bill Gates-esque zillionaire with a Jobsian fanboy following. He eventually rewrites and unleashes the MCP on the Internet cloud because he craves complete ownage. However, there is a young Eastern European hacker kid who steps up and saves the Cloud...and the world. Yeah, the young hacker would be kinda sorta based on Linus Torvalds.
However, that story was better and less hokily done as Summer Wars. When Funimation unleashes that in theatres...GO. Actually, come to think of it, Summer Wars was what Tron: Legacy should have been. And Oz is so much more visually interesting than The Grid 2.0.
