Is this why Sushant Singh Rajput-Parineeti Chopra's film 'Takadum' getting delayed?

'M.S. Dhoni: The Untold Story' actor Sushant Singh Rajput has a lot on his plate right now, so do Parineeti Chopra and Irrfan Khan. As a result, their film 'Takadum', to be directed by Homi Adajania, seems to have been delayed by a year. Sushant is currently prepping for his next 'Chandamama Door Ke' which will go on the floors around May this year. Sushant plays an astronaut in the movie and he has been posting about it on his Instagram handle.
He will also begin the promotions of his upcoming film 'Raabta', starring Kriti Sanon, soon. Meanwhile, Parineeti will get busy with 'Golmaal 4'. Irrfan will soon begin the shooting of 'Hindu Medium'. Hence it seems that Homi's 'Takadum' will take quite some time to see the light of day.
