Do think most AAA titles will continue on the path to achieve hyperrealism, but there will be a point where you just can't improve on it. Which is why I always prefer unique approach to graphics. Hand-drawn, Cel-Shaded, Low-poly stuff stand out way more.
hyperrealism in games is bound to dry up. people are going to get bored in hyperrealistic games because it looks like real life. you see that everyday bro. people wanna look at flashy colors and pixel art and stuff like that. AAA games are going to keep getting more stylistic over time, im sure of it
