Does anyone think it's likely that Batman has been laying low for 8 years and hasn't been doing much? His intention seemed to be going into hiding to some degree after TDK. I doubt he had 8 years in mind, but I could see it.
I think that is exactly what it is and what is implied in the Empire magazine comments. The preview clip with Gordon in the hospital bed seems to support that as well. Paraphrasing, Gordon said that "we were in this together, and then you were gone. The Batman needs to come back."
To me, that combined with the Empire magazine info, seems to indicate Batman has been gone all that time.
I find that to be a very different approach which opens up all sorts of questions and possibilities. At first blush, I didn't like it, but thinking about it more, if Batman is timid, out of shape a bit, and fights Bane, loses, but is seen defending Gotham by the Gotham people, and then comes back and ultimately defeats Bane, he'll be the "hero Gotham deserves."
But to be frank, I think there is a lot to this story. A LOT more. The Ra's Al Ghul thing WILL be revisited. I'd bet almost anything on it. The story is coming full circle.
