Is it different for TV series?
I saved NCIS season 10 over a year ago and it will also release in August. Season 3 of Walking dead has still not released.
Depending on the network/ production company the two most common release schedules I’ve seen for TV are 2 or 3 months after the last episode of the season airs, or 1 or 2 month prior to the first episode of the next season airs. Walking Dead (and all the AMC shows) I know is on the right before next season schedule, don’t know anything about NCIS.
