Which Khan might actually do lesser movies in the near future?

Why do I feel it will be Aamir Khan then Saif with Salman and SRK following! So yes the khans are irreplacable and there cannot be any other star to compete with these names . But sooner or later they will do less numbers of movie as new stars shall emerge and probably occupy larger screen space. Now unless you are Akshay Kumar who does zillion no. of movies , You may struggle for sure to stay longer . But again the leads roles are always approached to the Khans first . The next league is all about Ranveer, Varun,Vicky,Ranbir etc.
