If Blue Sky cannot handle 4K, then it looks like Shaw may be deciding to stay out of the 4K market.
Some 4K content is becoming available elsewhere, and 4K TV sets are common and far from expensive. I'll buy a 4K set when the current one blows. So it looks like my choice is being made for me: cut that cord.
To me, Blue Sky looks like a "meh, skip me" sort of offering.
