Sandros confirmed the intention of hosting the series' third All-Stars game in January 2013 during production of Bali though the date had been pushed back to 2014 to allow a break in Production after India. Kirin will return to host iS Live! taking over from Jared & José and acting as an assistant to Sandy. Adrian could not commit due to work and did not audition.
Due to the surge of interest in India, the possibility of the third All Stars was placed on hold to allow room for a second Fans vs. Favorites or an entirely new cast. Sandy announced during the casting call for India
There's currently a great pool of potential castaways to choose from, so I am personally excited for the casting process, and the coming few weeks that's in store. Those who do not make the cut, who came so close but still so far, will be receiving an email from me with an extended offer to possibly play in iSurv1vor 20. Honestly, we have so many good people with only so many open spots, it would be a shame to not see some of you play"
Sandy confirmed the location and subtitle on October 12th, 2013. The application process has been retooled and are known as auditions for both new and former players which began December 2nd, 2013 and ended December 16th of the same year for Favorites with Fans auditions concluding December 22nd. At the India reunion, iS Alumni Heeral (Bali) & Stephen (Bermuda & Tasmania) revealed that Production will recruit former applicants to the series who were cut and a twist involving Battle of the Sexes (absent since Cambodia) implying four tribes (Male Fans, Male Favorites, Female Fans, Female Favorites) though this was later debunked as Sandy has confirmed 7 male and 5 female favorites for the cast (including 4 alternates) on December 16th, 2013.
The fourth season premiere of iS Live! confirmed four tribes will be in play, the draft for Favorites will be more diverse by season as opposed to "five Peru players back together" and a season of firsts mixed in with elements from earlier generations. One of the originally cast Fans, Naomi, withdrew from the game during the cast due to connectivity issues  she was replaced by Eric who would later become a Favorite in Tibet.
After Tyler was voted out on Day 15, the remaining players were given the opportunity to mutiny from their current tribe to the other. This event led to rumors of the game being unfair and questioned the legitimacy of the series. After the results of the Mutiny were announced Sandy followed up with screenshots of the Production area stating when the twist was planned prior to the game starting stating "If you think I would hound each of you to keep the game fair, and put rules upon rules in place - just to turn around and change up the game to suit what, my needs? Because yanno, I'm playing and that makes so much sense" and extended an invitation for any current player to leave the game to prevent this occurring in the future. The castaways were then reminded of the Rules & Regulations which the remaining fifteen had signed previously clarifying the behavior of Production. Since that day, the situation calmed down and the game continued as normal.
