Well, he admitted one thing, PS4 is faster, not perhaps by 30%+ but it's faster nonetheless.
(And by the way Direct X is... well, I'm not exactly sure if the most optimized API out there)
Don't you think actual performance depends on hardware and software ? Do you think Sony is on par with "World largest software" Microsoft ? Do you think Sony is good at Software ?
ps 3 is better than xb 360 in term of hardware but it does not make any difference in the real World.
Don't you think "Cost cutting and making loss Sony" will have more research than Microsoft ?
Do you give any real functions, that ps 4 provides and xb 1 cannot ?
All answers are No.
