A few days ago Bethesda announced their future plans for Fallout 76 in the form of a roadmap.

Firstly they will introduce something called seasons where you unlock ranks to get stuff. If you got more money than sense you can pay your way forward:
Bethesda said:If you join a Season late and want to catch up, or if you just want to progress more quickly, you will have the option to spend 150 Atoms to immediately unlock the next rank and claim its reward.
They will also introduce two new power armors, one for captain cosmos and another one for the secret service.
Lastly the Brotherhood of Steel will for some reason turn up in Appalachia in an update called Fractured Steel.
The show goes on!
