People will flock to the theatres if a film like Sooryavanshi or Radhe releases, but the government will impose some restrictions of the capacity allowed.
If this rule isn't imposed, then people from the mass centres (i.e. Single Screen Audience) will go to the theatres and will not care about the situation. If you can see long lines when wine shops opened in Mumbai, then the same can be expected for films. People won't care about the virus, they just want entertainment from their favourite actors.
But this isn't going to happen for sure. The government will put a capacity of 50% (max) in theatres and for such big films, the producers shouldn't take the risk of releasing them. A test run is needed first by Independence day or August end, release some older blockbusters and see the response to win the confidence of the public.
Diwali is just 3 months away and with the number of active cases not reducing, I don't see the government letting go off the capacity rule. So in other words, I don't expect Sooryavanshi to release this year
