Assuming both the Xbox 720 and PS4 share the same CPU, and PS4 maintains at least a 50% lead with the AMD GPU, the above statement is a mathematical impossibility unless MS pays $ to 3rd parties to purposely subotage 3rd party ports to PS4. Since the GPUs are likely coming from the same AMD family (i.e., HD7000 series), it's impossible to make up for the graphical performance gap. Some possible scenarios how Xbox 720's game may look better is if the CPU is in the Xbox 720 is much better and/or if the OS on the PS4 is horribly inefficient negating all of the processing power advantage of PS4's GPU or if the developers can't figure out how to recreate "DX11" effects in PS4's OS environment.
Considering Xbox Live fees vs. free PSN (or PSN+ offering way more features like free games over Xbox Live), and if PS4 has superior GPU, MS is going to have to do something spectacular or market the **** out of their console to make it worth buying over PS4 if their prices are similar. Without PS4's 1 year delay and $600 price tag, MS's key advantage it had with 360 over PS3 are completely gone.

Seems like the Nextbox have "special sauce" units to help and free up the GPU... so less work to GPU... in the end the performance is near the PS4.
It's like that...
PS4 power: 5 task per cycle
260 power: 3 task per cycle
You have to run 5 tasks in both GPU but the Nextbox can do 2 tasks in the "special sauce" units... so at the end both give you the same performance. Of course that a dummy example lol... and these tasks are not for graphics at all (it is but not shaders specifics)...
Another point is that PS4 will reserve only 896 shaders units (1.4TFLOPS) for graphics... the others 256 shaders units (400GFLOPS) will be free to developer use for anything (graphics, GPGPU, etc).
At the end what will show how good the console perform is the optimizations and full use of the hardware.

I don't how it's possibe, the memory is a huge advantage for ps4 and you have 6 more cu;s i just don't see how ps4 won't have a nice advanateg but its too early to make the call, i really don't believe in special suace with out an explanation, most of the time its just wishful thinking.
