"Rick and Morty" is set to return with more episodes, but not anytime soon.

A few months ago, Adult Swim has finally decided to renew "Rick and Morty" Season 4. The network ordered a total of 70 episodes which only means that fans are set to see more fun and adventures in the adult animated science fiction sitcom.

"Adult Swim has made a long-term overall deal with the creators that will include seventy new episodes of 'Rick and Morty' that follows a sociopathic genius scientist who drags his inherently timid grandson on insanely dangerous adventures across the universe," the network said in a statement after renewing the series. However, there's no official release date.

According to Varun Malhan of Otakukart, the fourth season might be due for return in October 2019. This is still not official until Adult Swim confirmed it.

Ryan Ridley, one of the voice actors and producers, feels the same way. According to him, writing new episodes is time-consuming, so "Rick and Morty" Season 4 might not be ready until 2019. He didn't give a month but guessed that it would be at the end of the year.

"I know how long this show takes to write, let alone animate," Ridley said in an interview. "I'd be surprised if there was a fourth season on the air anytime sooner than 2019… late 2019."

It's almost a year since "Rick and Morty" Season 3 finale aired. In the said episode, Rick was up against the U.S. government.

"I don't want to poison the well but the finale is a great episode that we finale-ified when we realized we weren't going to be able to make 14," show co-creator Dan Harmon told EW about the said episode. "It's Rick in a conflict with the president of the United States. Keith David returns to reprise his role. And that's the main story of that episode, Rick vs. the United States."

"Rick and Morty" fans should continue to watch out for its official return. In 2016, the network and producers aired its premiere episode on April Fool's Day without any announcement which surprised many. Last April, the network released a parody episode to tease about the series.
