Tron 3 Video?

Attached to the upcoming Tron Legacy Blu-ray is a documentary (well in the Tron world), of the people of Encom and the disappearance of Kevin Flynn (Jeff Bridges) and the rise of Sam Flynn (Garrett Hedlund). So if you aren't nerdy enough to watch all ten minutes of this fake (but real in the Tron universe) documentary, it takes place after the original Tron to right after Tron Legacy, possibly revealing the initial story for Tron 3... entitled The Next Day.

As for Tron 3 actually happening? I know Disney is mulling over it... but Tron: Legacy was a bit of a disappointment critically and at the box office (but not totally).
