Since this is a Best Buy exclusive Blu-Ray set for the time being and Warner Brothers has not released any audio/video specs or much information about this set, I figured I'd post here to get an official answer. If the discs are all the same as the ones currently available, nobody is going to buy the set since you can go to Walmart and buy all the films there on Blu-Ray for $40 or so. If the discs are the new and improved versions that other countries have, then it would be nice to know so I can go out and buy the set, specifically to get a proper Blu-Ray of the third film which never got lossless audio in the US despite every other country getting a lossless surround track.
