update roll-outs are factor of several things:
When the quest was produced - batch date (earlier batch dates are prioritized)
Where you physically live - server availability (oculus will roll out typically in cycles to not but over demand on servers)
Reported bugs and fixes - So oculus might fix bugs as the rollout starts then - release better versions as needed.
It can take up to 3 to 4 weeks for everyone to be adopted on particular update.
If you have the update file on your computer and know how to boot load an update you can do that if your impatient, but i would advise as your better off to get the update when rolling changes are final.
