I picked this set up from Amazon. It comes with a nice little booklet as well as the three films nicely transferred onto BluRay. I haven't watched the films yet, but I have watched some of the special features. I particularly liked the feature on the Batmoblie in many of its incarnations.
I am looking forward to watching the films in succession again. I've really enjoyed Nolan's trilogy overall and if nothing else I like the generally coherent and comprehensive world he created for Batman. Sure it isn't real and still takes liberties, but it often seems like it could be real. Nolan straddled that line nicely enough.
It will be interesting to see the next direction taken with Batman and his world.
