It honestly doesn't feel like the full vision Nolan wanted. Certain moments don't quite get the running time they deserved, and that hasn't been a problem in past Nolan films. I suspect IMAX limitations are a factor in the length of the cut, lots of little things from trailers and tv spots missing too.
I think because of IMAX limitations the cut on the Blu-ray will be slightly longer, but not enough to justify calling it a new cut. Maybe 2-3 minutes extra max.
