As of now there are no plans to add a Villain area to a park. Every few years "confirmed" rumors as to a Villain themed park or a "nightland" park to be built surface. Nothing ever comes of it. Disney also just spend MEGA bucks revamping Space Mountain and all WDI parks so no Tron items happening there. I have seem some of the most recent Fantasyland reno shots from overhead and it is all to plan.
