Is it a possibility that Prachi was ousted because she is a Zee actor? It happens in Indian Idol when good singers are eliminated sooner because they appeared on Zee srgmp at one point like Amey Date, Rahul Saxena.
I think even Ronit will go out soon because he is a Star actor. Sony just wants popularity of these actors to increase their TRPs and they have achieved that. Same with Jay Bhanushali who is also a star actor. There is no way that Sonali could survive another round. Her dances are most boring and also have no public support.
That leaves us with Negi, Sandhya, Mika, Sonali. The way I see it the competition would be either between two girls or two guys.
So finale will be either,
Negi vs Mika or Sandhya vs Sonali.
