Yep, as of Batman #700 Terry succeeds Damian Wayne as Batman. There was no mention of Bruce's son since the character (in the mainstream DCU) had been created. Bruce has had children, just not in the mainstream wheb the show was made. In the past Bruce had a daughter with Catwoman Earth-2 and she became that earths Huntress, and I forget what his other son was but he was the do of Talia and Bruce... It might have been Earth-2. I'd have to go dig through them and find out.
