Just like Xbox One's "secret sauce" and PS4's "supercharged PC architecture", every single buzzword that will be used to sell these machines will be 100% bullshit. Their hardware will be obsolete from launch.
Pretty much. Like I said before though, it's not odd for them to focus on one area that is beyond what the PC can do for a short time. With Xbox 360 for example it was shaders, I believe. The way the PS5 designer was talking a while back I thought it might be memory/SSD speeds this time, but maybe they'll go all-in on raytracing. Who knows.
