I think Sky's long term goal is get rid of satellite dishes altogether and no longer need engineer installation. Sky Q would be phased out and not be an option.
There already there with the internet and phone if you have BT or Open Reach landline at your property.
Definitely their long term goal but that’s a long way off, lots of people can’t get good enough Broadband to stream TV. I think their next move will be releasing Sky Glass as a standalone product to use with ur own tv.
