I am praying there will be a release soon. I love this show so much. You can vote for it on tvshowsondvd.com. It is now number 12 in the rankings. There are also some videos on youtube you can watch.
At the SMK reunion this past October, the producers of the show said they were going to look into why it has not been released. Hopefully with their help we will finally see a release date.
WB owns the rights. At their last chat I think they said it was under considertation or they were looking into it. In other words don't hold your breath.
