Sounds like Obsidian Age meets the Az-Bats saga.
Oooh! I checked out a comic of the Bat-Man with Nightwing and Robin finding Tommy Elliot who now looks like Bruce. Tommy was captured and threatened to escape but Robin and Nightwing told him there's no escape with all the reinforcements Bruce's penthouse has (that's where Tommy is being held, you see). So part of the teaser image makes sense now.
