Cillian Murphy & David Warner To Be Villains In Tron 3?

AICN reports some details on the possible Tron 3 teaser trailer footage which includes three scenes. I don't consider these spoilers since it's only from a trailer and could end up being false. One of the scenes involve Qurra (Olivia Wilde) arriving at ENCOM to announce to the press she has spoken with Kevin Flynn. Another involves interaction between Alan (Bruce Boxleitner) and Ram (Dan Shor). The last could reveal the film's villains with Ed Dillinger (David Warner) plotting with son Ed Dillinger Jr. (Cillian Murphy).
