Sure, we're not going to get to see Tron Legacy until it hits theaters on December 17th, but that doesn't mean we can't drool over the posters and images from the movie that come our way before then. The question at this point is not whether this will be awesome, but whether it will be the next Avatar.
The poster above depicts one of the lightcycles from Tron Legacy. It's likely we're going to see a lot of these in the trailers to come.
It's hard to say whether or not this movie will be the next Avatar. It seems probable that before Tron Legacy hits theaters we will have at least a couple of movies in 3D. At that point we'll know whether Avatar was its own phenomenon (likely), or whether 3D is the next big thing (again).
Are you counting the days until Tron Legacy is released, or do you need to see another trailer before you're convinced?
