It is heard that both of them discussed on this recently and NTR reportedly asked Vinayak to drop the project. The key cause for that happens to be the flop of 'Sri Rama Rajyam'. This has cautioned the duo and they are reportedly feeling that the budget risk is going to be enormous.
However, there are those who say 'Sri Rama Rajyam' suffered due to lack of action and commercial elements. But if one looks at 'DVSK', the elements for entertainment are very high. For now, it looks like the project has gone into the cold storage and it might require few rounds of confidence for it to come back to life.
