Sony has some like Naya Daur, Kanoon Apna Apna, Qila, Ram Aur Shyam,(from Vijaya Productions shared with FTA) Ganga Jumna (bought back by Sony). I think Zee will air Shakti, Bairaag, Mughal-E-Azam as part of tribute.
Sony may air Qila, Ram Aur Shyam , Naya Darr , Ganga Jumna. FTA will air Gopi etc
Disney-Star may air Mashaal as a part of renewed YRF.
Viacom18 only has Duniya.
Zee can use their newly renewed Mushir-Riaz library for Dilip Kumar movies.
