Priyanka Chopra the heroine of the film says, "I think the sequel is a little far now. I don't think it will start soon. Everyone involved in the project is pretty busy now I think with other work." A source has revealed that Farhan is busy with Luck By Chance in which he is acting and also with his next directorial film Voice From The Sky. That's why as of now Don 2 is not starting. Looks like after Rock On, Farhan has more interest in an acting career.
The source adds, "Shahrukh too is very tied up now. He has to look after the promotions of his own production Billoo Barber, then he will do Karan Johar's My Name is Khan and then move over to his another production Happy New Year which Farah Khan will direct. He is also busy with his animation film Ravan. He does not have time for Don 2 at the moment but yes as everyone knows Shahrukh is ready to act in the sequel." So as of now it seems there are no hopes for the return of the Don!
