I absolutely want to see it. The OG Tron was cool for what it was, though I did find it hard to sit through a few weeks ago. It didn't age as well as I thought it might. Nostalgia couldn't hold it together.
 
Just saw the 3rd trailer for Legacy. Wow. If ever there was a movie that could utilize 3D, this looks like a fantastic platform!
 
Heck, after watching the QLEX for Tron: Evolution, I'm even interested in picking up the game. 

We'll see though. I'm sure real life and real expenses will step in and put the kabosh on those plans.
