Does anyone know when Season 6 comes out on DVD?

I take it your in America, so I can't tell آپ that much, being in the UK myself, but at the moment on TV Season 6 is up to episode 13 out of what I guess is going to be 22. The season finae is going to be two episodes back to back, in two hours, and is estimated to air on around the 20th May. Give a few months for a dvd release and آپ should have it سے طرف کی late summer یا September time, would be my best guess.
As for Season 7, we haven't been confirmed to get renewed yet, but let's پار, صلیب our fingers!! :) If we were to get a Season 7, it would start around September time where آپ are :)

Hope this helps x

Season 6 will be available sometime in September. There's no official تاریخ yet but I know it will be in September. If the دکھائیں get's renewed for a 7th season the premier episode will air also in September probably a week یا so after the DVD releases.
