With the beginning of the 6th season, the producers changed the process of the show. Now TVK comes out with 2 guests standing next to him and interviews them quickly (as a sort of "upcoming") for about 4 minutes. Then TVK sends them back to the backstage area just to call them back in one after another and the show begins.
Also the number of cast members has been tremendously reduced. The first season included between 10-16 characters per episode, that has been more an more reduced to 5 (on average) for the 6th season.
