Calling all 'Dark Knight' fans: start saving your money and circle your calendars now. In the fall of next year, Warner Bros. will release 'The Dark Knight Trilogy: Ultimate Collector's Edition' DVD and Blu-ray box set.

Details on the 'Dark Knight Trilogy' box set are scant at this point but as part of a press release celebrating their 90th year, Warner Bros. announced a Q3 date for the 'Ultimate Collector's Edition.' We can assume this will include 'Batman Begins,' 'The Dark Knight' and 'The Dark Knight Rises' but what else?

Hopefully there will be a bonus disc of new, never-before-seen features because, otherwise, what's the point? We'd also speculate that there will be some nice, fancy packaging as 'Ultimate Collector's Editions' often do. What you likely won't see are any Director's Cut as Christopher Nolan has ruled that out in the past.

What would you like to see included on the 'Dark Knight Trilogy: Ultimate Collector's Edition' box set? A gag reel? The original Bane audio?
