Trust me, don't read into it that much because your going to drive yourself insane with misinformation. A lot of these articles are to push False Facts around, and not explain the truth. The Xbox One is MORE then capable of pushing games out at 1080p. Look at the Wii U right now? They have more games at 1080p 60fps then both PS4 and X1 right now, with hardware that is not even close to X1 and PS4. The truth lies with the Game Devs, NOT MICROSOFT. These are the early stages and game devs have a learning curve to understand how to work with the hardware as we go. Don't make any assumptions at this point.
1) What people are forgetting:
Microsoft doesn't require game devs to run games in native 1080p
Why you ask? Here is why:
"A lower resolution generally means that there can be more quality per pixel. With a high quality scaler and anti-aliasing and render resolutions such as 720p or '900p', some games look better with more GPU processing going to each pixel than to the number of pixels; others look better at 1080p with less GPU processing per pixel."

Awesome example is the IGN BF4 Graphics Comparison video I posted above:
2) Sony aiming for 1080p and 60 FPS with all PlayStation 4 games

With good common sense you can understand where this is going, but just incase your having a hard time, this is not leaving the Game Devs the same freedom. This is why BF4 on PS4 is 900p, and not 1080p. When we all know the PS4 is more then capable of running games at 1080p.
And as far as "THE POWER OF THE CLOUD" which A LOT of people don't understand or know about. I am hope that my post here will help you understand fully more of what the cloud is up too.
So in a short explanation:
The Cloud Service will give Xbox One 3X TIMES the performance. Some of you might find this hard to believe, but the Cloud Service is the equivalent of 3 Xbox One's at the same time for game devs to use in the "future", here is a link you should read to understand this further..
