This is less to do with hardware and more to do with an ancient id tech engine (10+ years old), yes its been tweaked over the years but was never designed for this architecture. No doubt they will strip it down and start again.
I didn't copy and paste it, I wrote it and it is factually correct. People who say there is no discernable difference between the two need to look more closely. As I stated above, the developers are doing a good job at hiding the flaws in the XB1 version by increasing black levels and bloom but the lack of detail is obvious to anyone comparing still screens, and will be obvious to anyone looking at the consoles running in real time, rather than on video recordings that blur detail due to compression techniques.
In any event, factual hardware differences cannot be argued with. It has been known for some time on paper that the PS4 is superior from a hardware perspective, the only question being how much this would translate to in practical terms and whether developers would hardlock PS4 games to run at the same level as XB1 variants on multiplatform releases out of Sony/MS loyalty politics (for BF4 and COD: Ghosts at least - EA and Activision being the largest 3rd party publishers in the games industry by a long way - they have decided not to do this, which is interesting but also unfortunate for MS really).
If you're attracted to purchasing a console for its potential to allow you to wave your arms around in the air and pretend you're getting some exercise, fair play to you - personally Kinect and Sony's equivalent doesn't interest me in the slightest. I purchase hardware based on technological superiority and likely market domination. PS4 is the clear winner in the former and I suspect the latter will also be the case (pre-orders for the PS4 certainly outweight the XB1 by quite a distance and that's before the new information has come to light).
When it comes down to it it is your money so buy what you prefer; if you enjoy using Kinetc then go for it. Bear in mind, however, that there is already a confirmed hardware gap between the consoles, XB1 is rumoured to not be able to output natively rendered 1080p content (due to COD: Ghosts not being a particularly intensive game but the XB1 version being rendered at 720p with PS4 being at full 1080) and MS is charging more for it.
Be interesting to see what the landscape is like a year after release to be honest. I think MS may end up leaving a large enough hole in the market for Valve to successfully enter and take a sizeable share with the Steambox, but we'll see.
