I don't know if I see DC taking Bruce completely off the board, even if it'll be temporary like all the other times before. I don't see them taking him off for the same reason Marvel couldn't take Peter Parker off the board, even after Miles Morales came to the mainline and they were replacing most of their heroes, he's their cash cow. No matter how bad things in the comic industry get one thing remains the constant, its that Batman sells, and he sells like crazy, which is why the whole franchise is built around him. And there's still the unknown factor of Tim Fox, will he have great appeal, will he bring in the sales like Bruce will? That all remains to be seen and I guess DC will test that out with Future State.
