Revenge Of The Fallen
This is according to the folks over at SlashFilm and their sources.
While not a big fan of the Transformers franchise, be it the toys or various cartoon and comic book series, I do like the sound of the title. Very pulpish and not too spoilerish. All we know is that someone, presumably to who has fallen, will be extracting revenge.
Transformers 2 is currently filming on location in the Allentown/Bethlehem area and will begin shooting in Philadelphia next week.
