The extras for Batman Begins are all the same everywhere ever since the DVD, and they're in 480p too on BD. It's 8 featurettes, Tankman Begins MTV Movie Awards bit, and 3 previosly hidden on DVD as easter eggs 1-2 minute videos.
I think Blu-rays actually lost a bunch of photo galleries from the DVD (but gained an iMAX prologue, the only new feature in HD).
I'm actually amazed how you don't have one, I got a dozen probably, and would give you one if we were in the same town/country.
