I guess the people who would be able to make it to top would be-
Rashmi Desai- I have seen her in ZNKD and she is a superb dancer. She actually dances really well and is very graceful.
Karan Wahi- He is a good dancer and i guess he will make it to top 3. Plus they need a chocolate boy in the show.
Avika Gor- She is a good dancer though she's got Sanam as a choreographer but i still think that this pair would work.
I really dont think Jay will be chosen. Why? Because i read that Jay is very soon going to do a show with Colors and i think they are bringing him in JDJ for this one week to just make him more familiar because he was absent from the screen for sometime after SGP.
Neha Bhasin doesnt have much chances as others are more famous. Dunno how she si dance wise.
Rithvik is already doing PR and he is actually playing the lead there. i dont really think he would be able to manage JDJ and PR but but but i still think Rithvik has teh chance to make it to top 3. I somehow feel that it will be between him and Avika for the 3rd spot.
