I still we're years away from Sky going fully IP with Glass/Stream as there's still a customer base willing to pay silly money just to watch in HD on satellite, along with those customers who live in rural areas with slow internet speeds still which wouldn't be enough to stream Stream in HD before you even get to UHD, so I can't see them leaving those viewers to Freesat.

However those who are lucky to have a decent enough internet connection using VDSL or full fibre can see the potential for Stream to be the successor to Q with great PQ on the vast majority of channels. Even the SD channels are at least DVD quality when you consider Drama for example is 544x576 on satellite (and Freeview).
