I think I've figured out what Morrison meant when he said Batman would meet a fate worse than death, and I'm not sure if this theory has been propositioned. In issue #682, we have the Lump probing Batman's mind in order to create an army of Batmen for Darkseid, right? Well, my guess is that next issue, as was hinted in this one, Bruce figures out what is happening to him and, having prepared himself in the past what to do if he was ever psychically attacked, such as if the Martian Manhunter went rogue, he makes a mental image that creates a feedback loop and takes out the Lump.
However, by doing so, Batman becomes a vegetable.
Think about it. He wouldn't be able to walk, dress, bathe, or do anything without assistance. He wouldn't be able to speak, or write, or communicate in any way. He would see and hear and feel but be unable to respond. He would be alive, he would act alive. Just a mind trapped within his own body, unable to break free. In that sense, he makes a heroic sacrifice, doesn't actually die, allows a logical reason for why there needs to be a replacement, and also allows for the possibility for him to recover and come back some time in the future.
Also, I think most people believe that Dick Grayson is very likely going to be the "new Batman," but what if he is not Bruce's choice of a successor? What if it turns out that, according to Bruce's will or if anything should happen to him that makes it so he's no longer able to be Batman, it's Tim Drake who is supposed to take over, that he has the will, the determination, and the intelligence to do the job, and merely wanted Dick as a mentoring role. Dick, believing that Tim is too young to take on the responsibility of being Batman, decides he has no choice but to be Batman himself, much to the chagin of Tim, who would think that he's overstepping his bounds and, in protest, quits as Robin and adopts the Red Robin identity. This, in turn, forces Dick to select Damien as the new Robin. Also, Alfred is gone, chosing to take care of Bruce while he's in his catatonic state, which makes Dick turn to Oracle to act as a liason/operator. What do you think?
