Easy to say now but not in the year lead-up the Xbox division has had up until the launch of this thing. Lot of people there were hoping this would turn the tide. Especially after the dismal sales of the PS Pro.
Mmmm, no. It was easy to say then as well. The whole "people will jump on a chance to upgrade their consoles a la PC!" was tried by Valve and nobody bit (because Valve
totally fucked it up, IMO). Which was a sure sign that nobody was gonna jump on upgrading their PS4->Pro or X-box->4K unless their launch/cheaper console broke.
It doesn't matter about the exclusives.
Nobody besides Videowhores gives a shit about 4K. See the Steam User chart of the resolutions, a lot of the majority of the Steam userbase is using 1080i because it's the "cheapest" HD monitors around now a days and most couldn't care. Could their hardware do 4K?
Maybe/maybe not, depending on the year their built/specs, but a lot of folks
simply don't care about 4K.
