Motion blur. When this became viable it seems like every FPS started having a motion blur effect in them, thankfully usually with a setting to turn it off. Most of the time all it did was lower your framerate and blur the image when making sharp turns. Sometimes it was used for tunnel vision when running.
Depth of field is another upcoming thing that's going to get overused. For now it has been just the bane of ReShade/Sweetfx effects (hell, just look at the screenshots threads in this forum and you'll find plenty of it) on PC games but now that the consoles have enough horsepower to use it we will be seeing it applied by developers. Metal Gear Solid: Ground Zeroes is a serious offender, you have to mod a file to get rid of the effect on PC and the game is much more pleasant to play after that. I hope that they have a setting for it or severely tone it down in Phantom Pain.
I don't get game developers insistence on replicating every camera anomaly as an effect. Wouldn't the "camera" in most games be the player's eyes, which don't have things like severe motion blur, chromatic aberration and tons of lens flares.
