I hope Trent sees it fit to release The Fragile 5.1 mix some day. Granted, he seems less into the idea than he did in the mid-2000s when we got The Downward Spiral and With Teeth in surround, but we know he's worked on it - he Tweeted about working on with Alan Moulder back in 2009 or, I believe. So it's not exactly a pipe dream. I don't honestly believe we'll ever see it at this point, but as a fan of the format, I'd like to dream.
