Well, they should include the major versions to please everyone-but they won't. For a simple fix they should just stick to the 97 mix but use the DTS version and have it uncompressed. But they won't.
For a really badass huge mix they could use the 70mm mix as a base and then add in their precious SE elements for the new scenes and finally release it as a new 7.1 uncompressed mix. but they won't do that either.
So we'll just wait for this flawed new release....and once again show them how it should have been done.
