I cannot make a list as there are so many but would love to have Leader and Son of India on Blu ray.
And Do Boond Paani with Simi Garewal.

Definately:
1. Kudrat (Rajesh Khanna, Raj Kumar, Vinod Khanna, Hema Malini, Priya Rajvansh, )
2. Sarkar (Amitabh Bachchan, Kay Kay Menon, Abhishek, Katrina Kaif)

Maybe:
1. Anari (Raj Kapoor, Nutan, Lalita Pawar, Motilal)
2. Kaalia (Amitabh Bachan, Praveen Babi, Pran)

PS: Ofcourse this is subject to New 'actual' High Definition masters. No upscaled nonsense. I bring this up, only because the Indian video industry is quite capable of doing this.

can we add Dil Chahta Hai (non T-Series version) to this list

Too many films to list its seriously disgraceful that there are hardly any movies available on blu-ray. The rest of the world is busy restoring their movies and releasing all new releases on blu ray regardless of said movies box office performance and here with Indian blu-ray we count ourseleves lucky if we get a decent print. Regardless of what people think of their PQ/AQ YRF are at least trying to get their library out on the format. Theres also Eros but they only release big earning movies on blu-ray why cant there be a Sajid Khan styled blu-ray full of features and commentaries for the classic movies?
