I wonder how many people actually play their console on 4K Output devices. I play all my consoles on my full hd video projector, so neither of the new beefed up versions of the ps4 or the xbone are really exiting to me.
I personally don't, as I have no devices that can output to 4K, so no need for a TV. Also, my current HD TV are fine, so unless one breaks some time soon, I have no plans to upgrade any time soon either.
As for my friends who all game on Live and PSN, they actually all have 4K TV's. So while I don't think the upgrade is growing as fast as HD did originally, there is a smaller segment who want's the latest and greatest, and I guess this system is made for them. MS has more money than they know what to do with, and I think more than anything, this system is a middle finger to Sony for stealing their thunder this current gen. And since the PS Pro, wasn't that well received, MS is showing what they can do. I don't know that it will really make them much money, if any, but I don't really think that was their point.
My current plan is to get a PS4 slim this holiday, if I can get a good enough deal, and in that situation, the ONE is probably years away for me if then, so maybe by that time, I can get the Scorpio cheap as well. When you have a backlog like I do, buying new systems makes no sense what so ever. LOL
