"Without giving anything away, we have serialized stuff we check in on now and then that’s sprinkled over the top of strong episodic episodes," Roiland says of the 10-episode Season 4 in an interview with EW. "To fans of the show, they’re going to want to watch them in order." Harmon says of working on Season 4 after signing a deal to produce 70 more episodes: "I think it’s safe to say without fear of being wrong that the gap between seasons 3 and 4 will be the longest and last time that it’s ever so long that it’s ridiculous. I don’t know how fast we can do it, but I know it will never be this long again. There were so many things that had to be settled before we even started season 4, and it’s really safe to say — as Justin says — we’re literally writing season 5 while finishing season 4 just to force ourselves to commit to a certain schedule. Not to get anyone’s hopes up, but it is structured into our deal that if we’re going strong and fast there are options to deliver more episodes at a time."
