However, there is a buzz that junior Bachchan will replace Saif and will match up to the attitude of the character. Khan left the project because he has got extremely busy with his home production titled Agent Vinod, which also stars his girlfriend Kareena Kapoor. So, Saif has enough good reason to move out. However, the sequel is expected to have Kareena and her once rival Priyanka Chopra.
Race 2 is still in the scripting stage and Abhishek is still under consideration so who knows what the final cast would be. The filmmakers are trying to keep the original glamorous touch to the sequel also.
Saif has taken the decision at the right time when the movie is still in its pre-production stage and the makers have enough time to decide on his replacement.
