So moving to DVB-S2 will allow them to continue some SD channels like Challenge I suspect so it can continue on Freesat and some of the paywall entertainment channels, which allows them to continue with their £9 HD charge for Q and HD+ customers.

I'd speculate it'll be Sky branded Entertainment channels that start to go HD first only such as Nature where watching in HD would be the most benefit but wouldn't be as noticeable as if they went for Showcase or Max first.

I would say Sky Atlantic would be the likely channel to go HD only, since that channel is only for those on Sky or with a NOW entertainment membership.
