I've actually played fairly old games that both lack load time and have impressive AI.  The reason these things don't seem to exist right now is because of the focus on graphics.  We are past the point where impressive graphics can make a game better.  Instead we are at a point where the best graphics only make a game worse.  This is because development budgets are the really limiting factor and not machine hardware.  The more money that goes into developing graphics, the less there is for other aspects of the game.

I’m not fussed about graphics now, they’re pretty good for what it is now, but I would expect more consistent frame rates, and 60+ FPS in fast paced games/ shooters from now on also less huge FPS drops/freezing/crashing the game as showed in some games this gen, especially in large crowded areas like assassin creeds unity etc.

That's a valid point. Hopefully, the evolution of development environments will mean that they will need to work less on better-looking products and focus their attention on other aspects of games. Time will tell if this is the case, though I think that a focus on faster memory and CPU's is a clear sign that big changes are coming Let's hope for the best. In many ways this generation was about perfectioning what was done thus far, and IMO they excelled at this.

What? It's true, sort of.

Yeah, but at what point it doesn't make sense to pursue more graphics? Making great graphics is great and time consuming, and at certain point most people are not going to care above a certain level of detail. How viable is the continued increase of graphical capabilities after a while?

I am sure we will not see a another crazy evolution or ultra improvement not because the hardware is weak , but the requirement to achieve the goal is close and already achieved. We just need to improve performance, and focusing more on Smart AI for enemies, and NPC. Super fluid animation, crazy fluid weather effect , Seamless world transition and open world with extra detail full of living NPC. Also living , breathing world and super detail physics.

Yes, people buy the Nintendo Switch for the 720p @ 30fps experience.

I meant it in the sense of deminishing returns. If a developer spends tens of thousands of man hours and millions of dollars to craft a game to be the most beautiful and graphical astonishing game ever made, it's not going to sell much more than a game that just looks great, and the difference in resources needed is clear. At some point, the investment ins not worth it, so why bother improving the graphics?

I don't particularly care for shinier graphics. It's never the reason I buy a console, I follow the games.

The goal is to achieve photorealistic graphic .which i can say current gen  already can do decent job. Game engine like Frostbite engine, Unreal, Capcom Resident Evil Engine with scanning etc already did fantastic job.
