Unfortunately it is so expensive I don't think we will see anything else in Tomorrowland until 2030...they are already saying TRON won't open until 2022... It was a crazy expensive mistake...the money would have been better spent putting new relevant to the area attractions in the Stitch building and MILF. doing a complete re-dressing of The Peoplemover show sets, and then turning the Circus Fantasyland area into a complete Neverland section with a new Peter Pan ride (or double ride)...I can agree with it being very short, the thing about me is that TRON and TRON Legacy for me is one of the most underrated movies. So seeing any kind of representation makes me happy. Also, I just really want to ride a Lightcycle.
I can also agree Tommorowland definitely needs attention. Hopefully TRON is a harbringer of things to come.
TRON would have worked better at DHS or EPCOT...
