Exactly what Chameleon Guy said. They usually get good receptions with new players(Alejandro, Sierra for TDWT) and TDRI. TDPI ends up being the same and you have a reason for them to continue the same trend. Plus for the first three seasons, they might not have replaced the cast immediately but they were still taking out the people they weren't going to use and setting up their All-Stars so yes they were using the Survivor forumula(sort of)

Plus they already hinted at another All-Star season(which is most likely S6) so what can you expect at this point? They're going full-blown Survivor mode at this point.
