Why Karan Johar's loss will be YRF's gain?

Bollywood's Dabang Salman Khan finally broke the news himself. He tweeted that he will not be a part of Karan Johar's ambitious project 'Shuddi'. On earlier ocassion Karan Johar had announced that Salman will be a part of the project. Salman was supposed to do YRF's 'Sultan' but he was unable to find adequate dates for the same. If Salman leaves 'Shuddhi', he has all the time for 'Sultan'. And Sultan is a Salman-kind of film. It is about a wrestler and fans will see a fitter body of Salman. Deepika Padukone will be his heroine. So thats how Karan's loss is Aditya's gain.
