I completely agree with you about Lockhart and this coming gen.
No 4-6 TF lowest common denominator to worry about.
Both nextgen consoles are almost certainly going to have 10+ TF GPUs, 3+ GHz 8C, 16T Zen 2 CPUs (with less L3 Cache).
Super fast SSDs, changing how everything works as far as loading and running., and incredible potential for games designed in new ways using FAR faster streaming.
Not to even mention raytracing.
Well like you said, both consoles will have super fast SSD, both will have HW RT, greta GPUs and CPUs. All devs will try to conceive their games based on those hardware elements, this would allow for seamless streaming gameplay with no pop-ins or loadings, and RT may become even astandard. If something that gonna happen is that PC and PC gamers need to accomodate to those changes and with the upcoming games that will require those elements and not the opposite.
