So, taking what we know about what happened in the end into account, I wonder where they will take the story from here?
Some thoughts I had:
-Since Sam Flynn is now operating Encom now, I'd like to see the consequences of what that entails. Maybe have struggling with how to run a company, other companies competing with him, etc.
-This is where Dillinger, Sr. and Jr. could come into play. You could maybe have Jr. try to compete with Sam to try, maybe the elder Dillinger's way of getting revenge for being fired from his company.
-Definitely want to see more of the games this time around. As much as I liked them in the last film, I'd like to have them be more integrated and be more crucial to the story. Make them have more stakes, as well. They could even introduce a few new games, too.
-Quorra's relationship with Sam should be explored further in this film. Also, her being in the real world now should have some serious consequences. Some could maybe want to try and use this to their advantage. Maybe Dillinger, Sr. is looking for way to accomplish what Clu could not? Maybe he wants to become immortal? Who knows.
-With Flynn, it was hinted at the end that he wasn't completely destroyed. Maybe he could come back as some sort of Obi-Wan figure to Sam's Luke. You could have Sam learning from his father on how to use his godlike powers in The Grid. And if Dillinger Jr. ended up having to go against Sam in The Grid, they could engage in an epic User vs. User showdown.
-Considering that Tron was shown to return at the very end of
Legacy, I'd like to see him play a much, much larger part in this film. Maybe have him be a mentor to Sam and offer him support after Flynn's passing. Also, more of him being a badass.

So many possibilities for this new film.
