Alright. I'll agree with that. But when someone says "it" instead of "he/she", I'm thinking of something over someone. I got confused, because it does seem like he says its an adaption of Frank Miller's comic.
Btw. In year one, Batman is 25 years old. I don't know how canonical any of the comics are, though. I'm not really a comic buff, so I can tell you facts but I can't really tell you what they mean or how they relate to other comics, etc. Also, batman's bat symbol is a staple. Many iterations of Batman have had a very similar looking crest on their chest. Although, his looks similar in design, since it does look fatter than the normal crest. Google images can give you the answers you seek.
Also, according to sources, Batman is around 43 years old when the Justice League forms (and the next movie at this one is supposedly the JL movie). So this could very well be an older Batman, but I still don't think it will follow Frank Miller's retelling at all. Although, after LJ... who knows. Snyder could choose to bring Batman out of retirement, since he is 55 in The Dark Knight Returns.
