The Lone Wanderer, the Last, Best Hope For Humanity, the Capital Wasteland's personal Jesus Christ, the savior of The Pitt, the exterminator of the Super Mutant menace, the hero to all and savoir of all, is now in charge. Just a theory, but maybe Elder Lyons, being, well, elderly, died, and Sarah decided not to take over, preferring to continue leading her squad. Furthermore, they have The Lone Wanderer.

Going by the trailer, the Brotherhood is happily putting to use the massive amounts of technology that you've helped them acquire during Broken Steel, now having Vertibirds and the like.

That's more than enough logistics to fight a war. Presuming the airships we see in the first trailer also belong to the Brotherhood, that means they've begun manufacturing new tech, which in turn means they've both cast off some of the restrictions of their dogma and have built up considerable industrial infrastructure. After all, they do have a large manpower pool to draw from in the Capital Wasteland-individuals who are likely highly-motivated, well-trained, and well-equipped-especially if we assume a 'Good' ending to Broken Steel, where they also have command of huge resources of fresh water.

Don't count the Brotherhood out just yet.

The BoS does NOT have it anymore, and don't have the schematics to recreate it.

Liberty Prime was obliterated by the Enclave's Kill Sat.

This is the war the BoS is unlikely to win, even with Liberty Prime by they side, since The Commonwealth so advance that they are capable of making Androids- robots that can eat, sleep, piss, breathe and probably have sex.

Seems like something they'd do, especially if the Institute turns out to be evil. And it looks like the Brotherhood has appropriated Enclave tech already. The Brotherhood has gone to war with the Institute.While we don't know much about the Institute, we know that they're techies who run the Commonwealth. The Sole Survivor wakes up 200 years later, but everyone else was released - and massacred - over 60 years before they wake up at the start of the game.

Jossed: Vault 111 is another Cryogenic Suspension Vault.

Perhaps that's what Vault 111's experiment was? What's more likely is the old casting leaks that people initially balked at - they mentioned that the main character emerges into the wasteland from cryogenic suspension. Specials were generally non-canon: stuff like finding a crashed Star Trek shuttle or the TARDIS.

That was a special encounter, not a random encounter.

Time travel did appear in Fallout 2, where during a random encounter the player went back in time to sabotage the water purifier, causing the events of Fallout 1.

Given that the Commonwealth is a technological powerhouse, this somehow strangely not implausible.So, time travel in a trailer? Makes more sense as an important detail. Considering it's a sequel to a big franchise, it's abnormal to give a quick rundown of what happened in the past in the trailer, as it's usually assumed you know.

The trailer keeps flashing from 2077 to whatever year it takes place in. Law of Conservation of Detail, basically.
