Tron 3 in 2013?

Disney’s D23 expo never really interests me unless they’re talking about another Pirates of the Caribbean, which even now doesn’t matter to me anymore. Tron however is a different matter together. I loved Tron: Legacy even not having watched the original since I was little. It was visually stunning and had a pretty interesting story. Plus, when do you get to see a movie where Jeff Bridges is both the hero and the villain?
