We know that Disney filmed additional footage specifically for the DVD/Blu-ray release of Tron: Legacy, but the nature and intent was in some doubt.  It was first reported there might be a teaser trailer for Tron 3, but that appears untrue.  (Another Tron sequel still hasn't been greenlit, mind you -- though it's close.)  Some of this footage has surfaced online as a 10:27 clip  titled "Tron: The Next Day."  The focus is bridging the decades between the two Tron films, and the story ties heavily into the "Flynn Lives" viral campaign before Tron: Legacy's release.  Garrett Hedlund, Bruce Boxleitner, and Dan Shor make appearances.The current over/under on this leaked clip is about four hours, and I'm betting on the under.  So watch "Tron: The Next Day" while you still can after the jump.Via First Showing:-
