Haha I have just effectively described a trailer haven't I?

I just thought a prologue of extended footage, with scenes playing out longer then a trailer allows etc, might of been what was needed for a MoS prologue. If this film follows Batman Begins structure, i.e with plenty of flashbacks, the fact that it takes place over many years etc, perhaps it's harder to have a 1 sequence long, self contained prologue like the Batman sequels.
