Grant Morrison is coming back to Batman, and he's bringing Frank Quietly and Robin along for the ride.
I am really excited about Morrison returning to Batman. He really turned that book upside down on it's head, and it doesn't look like he's stopping anytime soon.
If you haven't read something by Grant Morrison, then I suggest you try All-Star Superman. It's one of the finest displays of what a comic can be. When it was announced Morrison would be on "Batman & Robin", it made you think he might be doing All-Star Batman. But, thankfully, this is a continuation of his Batman run.
The question is - who's under the mask? It seem pretty obvious Damian, (Batman's son) is Robin. But who's Batman? Bruce Wayne is definitely coming back, after his "death" in Final Crisis, but for the time being someone else is going to be using the mantle. I can see Dick Grayson being Batman, and physically he fits the bill. But a nagging thought keeps saying "Tim Drake". Well, I guess we'll all find out soon enough.
Here a link to an interview Morrison gave about it http://www.comicbookresources.com/?page=article&id=20487
