The latest move from Disney to promote the 3D CG flick has been to release a billboard style image of a lightbike from the flick.

Much like the content released thus far, we have no real context for the image, but hey…it looks cool!

Hopefully, Disney capitalizes on the hype soon. A 3D trailer attached to March’s Alice in Wonderland release would be pretty sweet.

TRON: Legacy hits theaters at the end of 2010.

EDIT: Here’s a SUPER High-Rez version! Click for realllllllly big!
