Be patient. Let them make some money in cinemas first. Then the Blu-ray.
May 24th is the scheduled USA release date. Depending on who else releases that week, that could change.
I have been pushing for release in theaters and home video the same day. We have that now, but it is pirates that are selling the home media. I think cinema goers will still attend if we do that. They are by far 18 to 25 years old, and have a strong desire to sit in the dark for a while with a member of the opposite sex. Home video is for the rest of us.
