Yeah I'm a huge fan of the oval as well and loved the Burton costume...so much so that a family friend made me one from scratch for Halloween complete detail even with Michael Keaton's muscles!
Trying to guess what Morrison is going to do is like discussing quantum physics...I don't think he's going to do anything that's been suggested so far. This is a new concept and I'm sure it will tie in with some kind of soul searching that Bruce has done over his time coming home. So far in the Return of Bruce Wayne mini-series he has barely said anything. I'm guessing when he arrives to present time his mind will clear and the Road Home will be something of a soul searching and he'll come up with the idea that will be explored in Batman, Inc.
