Will Xbox Series X and Playstation 5 big the biggest leap gaming has yet to see?

[SvennoJ]

I keep reading 2D to 3D was the biggest transition. However when was that transition? We had 3D vector graphics games, Battlezone 1980 vector graphics, I Robot 1984 polygons, Wolfenstein 3D 1992 had textures, Descent 1994 was 6DoF, and we still have very successful 2D games.

So what is considered to be the transition to 3D?
