I'm looking forward to s7 on DVD. I've been catching up with SG-1 this year after finally getting into it. With s8 on the horizon next week, I'm starting into s6 on my DVDs. I'm going to join s8 since I know most of the major spoilers of s6-7 and think I can follow s8 just fine.
Getting s7 and watching it on DVD will be a nice treat when it arrives though. Hate having to wait. I've gotten used to just walking into the store and buying the next season I need when I finish with the previous season.
