See from the first two I never got the feeling that this was a Bruce determined to take on being Batman forever. I always thought once he done his job he'd try and move on in TDK he was more than ready to give up the cowl because of Dent. And even at the end of TDK he was willing to give up being Batman for the good of the city of course Rachel's death and Harvey's downfall complicated things to the point where he only believed he had Batman left yet he stopped being Batman as he simply thought he wasn't needed. If Bruce was determined to make this his life work in Begins I don't think he would have given up.
So this makes the time gap easier to swallow as I just saw at Bruce thinking it was the time Batman needed to return.
