No it’s not. Season six came out last month, in keeping with the November/May release dates. Season** 7 **comes out in the spring. Unless your location isn’t really GA (and you live outside the US) you should be able buy it tomorrow if you wanted to.
I’m working on The X-Files (Santa will probably bring me season six) and Buffy The Vampire Slayer right now.
If they came out on DVD, as complete seasons, I’d probably also buy:
Rocko’s Modern Life
2 Guys and a Girl
I would at least consider buying:
Space Ghost Coast To Coast
The Young Riders (it was my favorite show when I was 10 )
