Heard from my sources that they will keep sports HD/SD ala carte, in other genres can't afford to separate from the bouquets.
Sun will be least impacted, they can just comply with NTO2 with minimal changes in the bouquet structure.
Star will be most impacted (evident from the fact that they have filed 4 different pleas on the same matter), and it will be a tough deal for them to package the channels in the new regime. Given the fact that they are already bleeding due to hefty IPL payouts, they will surely challenge the order further (if the same is against them).
For, Sony, Zee & NW18 I don't see much impact. However they are fighting it more for the fact that pricing control is moving away from their hands, and if they give in this time, if there are any further interventions by TRAI, they will have to adhere it.
All in all I feel even if one of them come up with the revised pricing, all of them will have to come with their revised RIOs. And I feel either Sun or NW18 will be the first ones to release the revised pricings, if the judgement is against the broadcasters.
