Rick and Morty could just be the most beloved modern day animated cartoon of the recent years. The reason for this is mainly due to the fact that this animation cartoon is created for older audiences and so it offers a unique genre. 

The new season, season 3 of Rick and Morty is going to be a big one! The show is gaining popularity and so it is only natural for the creaters and the producers of it to put in even more efforts to make their fans even more happy. 

There are updates mentioned by iTech Post  which are quite interesting to read. For instance, the first update talks about how there is going to be a Hawaii Adventure. Adult Swim released an official statement where Harmon mentioned how he demands of Adult Swim to let them draw their characters taking a trip to Hawaii. 

This at least confirms one episode which will entirely circle the state of Hawaii.

Secondly, a really exciting guest reveal of the show will arrive in a Drift. Not a drift of wind but the drift of a car. In Comic Con 2016 the creators of the show claimed how Vin Diesel is their dream guest star and they really want him to do a voice-over.

If this does become true then one can expect various flashy cars and automobile humor in an episode. 

Finally, after such a popular appearance in the show, Mr. Meeseeks might return back to the show for a comeback.  The creative team is constantly discussing the comeback of Mr. Meeseeks. As of right now it is pretty much confirmed that he will be brought back into the show. 

What is unknown is how one will do it. They are saying that since it is a come back it should not be irrelevant. Therefore they are discussing a new angle on it.

GameNGuide also mentioned how there could be possible delays to the release date due animation slow downs. There have also been 14 confirmed episodes.

Nonetheless, all of this will be confirmed when the show is finally released.
