Tron 2.0 is going to be shot ENTIRELY in 3-D. They are really excited about what they are going to be doing with the Tron world in 3-D.
With new technology, they can actually wear the glasses at the monitors as they shoot & it will show them exactly how the 3-D will look so that they can get exactly what they are looking for.
If there has ever been a world that 3-D would totally embrace, I think it would be the world of Tron. Specifically, we are going to get a first person view from inside of a light cycle in the film. That should be a lot of fun.
