That's true, but specific to the Quest 2 hardware is the much nicer display, lighter than its predecessor, its inside-out tracking is more convenient than setting up stationary tracking beacons (a-la Valve Index), its guardian system is nice for setting up arbitrary play areas, and it degrades more gracefully at low FPS than its predecessor by respecting 6dof of head movement at a minimum of 90fps at all times, reducing motion sickness.
