SKY's Now TV app will be on by summer 2014 apparently. Not that I will be using that. SKY go/player is likely one of my most used apps on the 360 so I do hope it will appear on the xbox one.
It mentions in the article SKY say they will consider future opportunities for SKY Go. Kinda looks like they are pushing NOW TV, remembering their prices for the brief time I used it they will likely make more money :P.
