The End of his career of course!
His notoriety has reached such a peak now that majority of movie audiences will avoid his movies, only his diehard fans will watch them. And producers, directors wont sign him anymore, expecting him to go to jail sometime in the near future. Who would want to invest money on a convicted criminal?
There are numerous cases pending against him, this drunk driving case is not the only one.
Anyway, all 3 Khans are reaching 50 and now is the right time to gracefully retire from hero type roles.
Aamir is already doing dad's role in next movie Dangal, SRK also is choosing "different" kind of roles now.
Its high time the Khans got replaced by the new generation of actors.
