It's the Bigg Boss house and big names are for sure to be attached to this one. But, who ever thought Dus Ka Dum host Salman Khan would switch roles and host the new season of Bigg Boss. With him on Bigg Boss 4, we think Dus Ka Dum will be stretched to end of this year or early next year. The Sony show will probably be pushed ahead with Kaun Banega Crorepati going on air during the same time. Sony is also planning to come up with season two of Iss Jungle Se Mujhe Bachao and Jhalak Dikhhla Jaa 4, which will hardly leave any room for Dus Ka Dum this year, but there is enough work for its host. With Khan and Bachchan swapping channels it’s going to one stiff competition on the ratings’ chart. There is also buzz doing the rounds that Colors had approached Akshay Kumar and Shah Rukh Khan to host Bigg Boss.
