Did anyone ask for another Hush?
Hush had a lot in common with an old Morrison Bat-foe called 'Whisper'. And Morrison, in an example of creative leap-frog, in turn created another Hush-like villain called the Black Glove in his current extended storyline.
How many evil manipulators were hanging around when Bruce was a wee lad? A story where they all bump into each other while peeping through his playroom window would be good...
Also there's probably an element of people waiting their whole life to write Batman, and when they get the chance and think they have a great story to tell about him, they find that they have to write, not Bruce Wayne - the real Batman, but the kid!
