It is one of the prestigious and much talked about film. With Ram Charan and NTR in it, with direction by Rajamouli, why not? The film is in its pre-production stage. The latest we hear is that there might be a delay due to issues in the script. 

Though the team is working in full force on the script, the delay is inevitable. With that said the regular shooting of the film will be pushed to December. Initially the plans were to start the film in November.
