Warner seems to be committed to producing at least two sets of TTA. The staff are being interviewed currently for the first two sets in one go. The first set's extras will cover the development of the series and characters. The second set's will focus on the creative team. If anyone has a particularly good question that isn't already known within the fan community, send it to me today or tomorrow and I'll pass it on. No guarantee it'll make the final edit, of course.
