This is rather significant since Universal has been a big player so far with HD-DVD. Finally. While the review here states End of Days has a somewhat dull sound design. The source is the key here. But at least we know now that while Universal has been HUGE for HD-DVD with releases and it's new HD interactivity, they are now doing Dolby TrueHD. http://hddvd.highdefdigest.com/endofdays.html#Section3 Salivating thinking about the plethora of Universal titles....(should have been on Serenity though .) This needs to become the standard for Universal. Good job!
