The "objects flying at the camera" is already a lot more toned down. There are two specific moments I can think of in Avatar; one being in the rerelease.
I remember first time I saw a 3D film, back when the BFI IMAX opened so some time in the 90s, the films were all objects hovering directly in front of you and zooming towards your head, because it was a gimmick/selling point back then. Moving past that is just the same as when colour first came out, having realistic colour rather than bright stylised colour.
