Quite a few interesting pieces of information regarding a third TRON have appeared over the last few days. This doesn't necessarily mean anything, but I thought it was worth bringing up anyways.
First, Joseph Kosinski recently revealed[] what "TRON: Ascension" (the third movie's title has now been officially confirmed) would be about.
Personally, I think that it sounds a little odd that they'd consider doing a TRON film that mostly takes place outside of a computer, but a third film would be more welcome than no new film. This new information will be a good addition to TRON 3's page.
Also, there's talk of the third film being a reboot starring Jarred Leto[]. However, these are early rumors and none of this is set in stone...
