Alright, so it's early yet and there are no guarantees there will BE a Tron 3. But I'm hoping there will be. It seems Legacy sets up a few things for Tron 3... or at least plants some seeds they could use if they need to.
What do you guys think/hope we'll see?
Since Legacy was about Flynn, I think Alan/Tron might feature more in 3. At the end as "Rinzler" disappears into the Sea of Simulation, his lights turn blue. I really think he survived. Maybe 3 will be about his redemption? Actually, Tron: Redemption might be a cool title!
I also imagine Edward Dillinger might show up. It seems strange to cast Cillian Murphy in such a small cameo role if there wasn't the possibility of his return. Since he seems to be a computer genius and may be disgruntled once Sam and Alan take Encom back - I can see him hacking into the Grid to become the bad guy of the next film.
It'll be interesting to see where Quorra and Sam's story goes. I was a little fuzzy on just how Quorra's digital DNA was supposed to change the world...
And finally, I'm hoping Castor and Gem (like any shady dealers worth their salt) had an emergency escape route to make it out of the End of Line club. I'd like them to come back for the sequel.
