One person I'm sure will be in Top 2 is Teja. Although many dislike her, you cannot ignore that she's popular.
Another contestant that is likely to be in Top 2 is Pratik. He is winning so many polls these days even against Karan. He's also supported by many celebrities. (I don't think makers want him in Top 2 though... they might play a dirty game to bring someone else in Top 2)
Karan Kundra used to be the favourite to win but after Umar's eviction, his chance of winning is not very high. I don't even think he'll even be in Top 2.
Although Shamita's fan following has been growing recently, I doubt she will get more votes than Teja, Pratik, or kk.
My final prediction:
Teja: Winner
Pratik: 1st runner up
Karan: 2nd runner up
Shamita: 3rd runner up
Rashmi: 4th runner up
Nishant: 5th runner up
