The title implies exactly what your fevered geeky mind thinks...they're FINALLY making a sequel to TRON!
Here's the bootleg crap video quality teaser from Comic-Con. I won't say anymore. You just have to see it.
It's hosted on YouTube, so watch it before the big-wig movie guys find out it's there and pull it.
Update 08/01/08: The trailer's gone again. I'll try to find one that I can host here instead of using YouTube.
