ComicBookMovie.com posted two different Videos of an interview with Zachery Quinto the first having a little more of the interview then the second which runs about a 1 minute 5 in time compared to 2:16.
In the interview he expresses his feelings on the long time between films which is a quite positive feeling that the long gap between films is good thing and it gap will let people breathe a bit and not to have them say "Already ? You know, again ?".
He also brought up some interesting ideas that possibly will be incorporated into the script. Of course this is speculation because he has no idea of what will be the story but hearing his ideas brings a level of curiosity to the project that is both exciting and healthy for the franchise.
