Chicken and Egg
The technical demos of 4k video that I've seen are incredibly good - however the content available in 4k is, for the most part, mediocre at best and I've got 1500 DVD's that look great at 1k. So where's the incentive to upgrade?
I can't see the justification in paying $100/month for the bandwidth for 4k video when there's nothing worth watching ... for some reason the entertainment corporations never seem to understand this.
