Considering Sports passes still do not have any catch up content, I wouldn't hold my breath!
Although Sky Go/TV from Sky on PS4 has catch up sports it certainly wouldn't be difficult to bring that aspect over to Now TV.
I would like F1 Sky Sports Channel upgraded to 50FPS on NowTV like the Main channel is now with boost I think that is definitely possible. Catchup for Qualifying would be very nice specially for races held in early morning but not sure how likely that is to happen.
To be honest, the F1 deal they've done before at £119 for the full season makes it £13.22 a month... for 24-hour access to all the Sky Sports Channels - It's great value. And whilst the quality it's stunning I still get a very respectable picture, even stretched on a 79" TV!
If anyone from Sky/NowTV is reading, I think that the above is a justifiable price for those of us that just want to F1 - Committing £34/month to watch 1 channel for 2-3 hours every fortnight won't do it for me
