So, with the release of the 18th season on DVD, do we now have a hope that the rest of the seasons will be released to us "dinosaurs" who want the physical medium? 
I really hope so. I haven't got this yet, but some say the introduction by Matt Groening hinting that it might be, since there was a massive protest against not releasing them on DVD.

If someone have the introduction I hope they can post it here, or verify that this is true
