Considering that the Brahman, the highest level of the old caste system, closely resembled 'Brahmin', and it's in the form of a mutated cow (the bovine is considered a sacred animal in India), I don't think Fallout 4 will see light of day over there.
And can you really blame them? From their collective perspective, Bethesda's basically taking a dump on their sacred animal AND a highly respected title of the old caste system by having a diseased, mutated cow species called 'Brahmin'. I don't know the politics of India with this kind of stuff, but I wouldn't be surprised if they refuse Fallout 4, or really any game that lets you kill cows period.
