I am not sure. They have not announced the rights holders yet. Looking at the variety, Viacom18/Sports18 might try to get F1 rights. But again just a guess.
In the past seasons, Hostar's PQ of F1 was very bad. Highlights were also not available after a week. No pre-show and post-show also. So it is better if someone else grabs the rights this time. Let's wait and see.
