Well, the GOUT was actually supposedly a Limited Edition, so it's not that surprising Lucas is finally making sure it gets phased out. I recall seeing some in a Borders store when I was there for the "Closing" sale. Anyway, with all the preservations/enhancements we have of the GOUT, the base disc is somewhat unnecessary.

As for the other DVDs no longer being available, well that's not surprising, the 2004 version is now outdated, replaced by the 2011 version. The good thing though is that we've thoroughly preserved the 2004...
