I'm looking forward to this release, the Futurama sets are typically very well done, I'm ready for this march 9 can't come soon enough, I suspect Volum 4, the final 1 will be out before years end.
The problem I've been having is that if I click "back" I lose my post! I spent about a half an hour typing a nice long review and now, *sniff*, it's gone. :frowning:
All Futurama volumes have already be released in R2 I believe, so the Futurama sets have been completed for some time. I do not believe that King of the Hill has as many Extra Features/Commentaries so Fox can release those faster as well. Fox would certainly like to release The Simpsons faster, but they have to wait for Groening and Co. to get around to recording commentaries and preping other special features. Once the Simpsons goes out of production, season sets will hopefully be released at a faster rate.
Groening and Co. have already recorded commentaries up to (I believe) season five, although it's been so long since I heard that that they may well be beyond that now. The most common explanation I've heard is that it has something to do with syndication rights but that's not official.
