I think she will be there for sure, here are my reasoning:
1) One contestant from Pritam's gharana has already got eliminated, this week so there is less chance that another one will get out next week
2) Yashita got the highest votes this week, so she can't drop to the lowest place suddenly
3) She sang with Aditya in the duet round, but they did perform terribly. But should be able to gather more votes
4) Is from Mumbai, and i don't think ever before that we had a finalist from Mumbai in any reality show
So will Yashita be in the top three?
