This reads like a TED talk full of hand-wavy marketing-friendly vagueness and ambiguity. May as well just say next-gen engines will be faster, better-looking, and cheaper to work with, leave it at that, and let history prove you uncannily prophetic.
It is weird seeing my hobbyist game dev and professional enterprise software world collide like this. Articles like this made sense when Facebook was willing to put up billions for VR services. But that was a bust, and now you have tons of consultants spinning their wheels. There is no reason any game studio or publisher needs to be told what game engine is good, I don't even think they care as long as they can make a good game. It's not a huge organization that you are trying to rally around some kind of decision.
