Query: Where is Season 4 on dvd???

I bought Season 1 as a casual purchase at Target. I didn't even know it was out. Then, I went looking for Season 3 a few months later and was so impressed that I grabbed it. Now, no sign of Season 4. Is it in the works or not coming out at all? I'm surprised because it's getting close to 2 years now. Bring on Seasons 4, 5 & 6!!! I want to see Edna's Edibles!!!
