For those of you who loved Tron Legacy as much as I did, theres gonna be this easter egg video on the blu-ray in april. Luckily we've got the video already leaked. It seems to be a teaser for TR3N or Tron 3 featuring Sam Flynn and some very special characters from the first movie, watch to find out.
Disney seems to have removed the leaked footage. Will update again if I find a working link.
If you've got a link that works tell me down in the comments.
