I think people are just a bit intrigued by the fact that there is a studio version of an extended JP solo that hasn't been released, since this is probably the first time since FII where DT has recorded something that they haven't released. It's also interesting to think that JP probably has a copy of the song with the full solo, since he had to practice and relearn the songs before the tour. It would be a cool thing for them to upload to youtube so we can hear it in it's entirety. They probably won't do it, but it would still be a cool thing for them to do.
