According to tvshowsondvd.com Fox will be releasing The Simpsons S20 as the next DVD set. No official release date has been announced, but Fox released the cover art: http://www.tvshowsondvd.com/news/Simpsons-Season-20-DVD-Blu-ray/12796
It should be noted that S20 was the first HD season (partially through the season actually). I never thought Fox would release later seasons so early! I do hope they continue to release the older seasons in chronological order as well (S13 and up).
