I got the Blu Ray a few days ago.
There are no extras at all, but I don't really mind, to be honest. Nothing very exciting about watching a bunch of guys in lycra jumpsuits with dots on their faces running around an empty studio to a green backdrop.
Another advantage is that there will be no compression issues, with all of the available data and space going towarRAB improving the pic and sound quality.
And to be fair it does look and sound excellent. I don't want 3D, I found it too distracting in the cinema.
And watching it a second time, I enjoyed it a bit more, it's good to be able to take time to look for little details you may have missed first time round at the cinema.
