Excited yes. I had the stand up arcade game in my basement for about 5 years.
With the exception of Avatar I have come to HATE, HATE, HATE 3D Movies. Largely do to the post-production, gimmick, charge extra at the box office bull $hit.
However, I have high hopes for Tron as a 3d movie, as the source material makes it the perfect candidate. (But honestely, it will probably be the last 3D movie I pay for, I simply find the format distracting and a gimmick.)
