QUAKE will (probably) sadly never return, because NuDOOM isn't DOOM, Its Quake
DOOM 3, DOOM 2016, and DOOM: Eternal are all Quake games, not DOOM games.
DOOM games are iconic for extremely limited movement. You can move fast but you can't jump or even look up and down. This was the case with Wolf3D and are, obviously, engine limitations. Quake comes out and revolutionizes everything.
Unlike Wolfenstein which (To my knowledge of RTCW and my experience with TNO/TNC) reworks the physics and gameplay for a more tactical, unique feel, DOOM has just adopted Quakes physics and movement identity.
I can't really explain it, but 3 and 2016 have physics and character controls similar to Quake and play more like Quake than DOOM. Eternal is a more evolved 2016, and therefore a more evolved Quake rather than DOOM.
The only NuDOOM this doesn't apply to is DOOM: The Dark Ages, which plays a lot more like 1993s DOOM than Quake. You're very fast horizontally but pretty weak vertically.
Could Quake return? Probably. But its identity has dissolved into the groundwork for DOOM, and since Eternal has peaked in gameplay, ID probably won't revisit Quake, let alone a Quake-based NuDOOM until they can somehow innovate on Eternals formula
