Bethesda tweets cryptic Vine video, says "guess again" to Fallout 4 rumors

It starts with a dizzying shot of barbed wire.

It starts with a dizzying shot of barbed wire. Then we see a glimpse of an LP—The Moonbeam Trio, directed by George Shackley. A quick Googling reveals that the Library of Congress has recordings. Then we see sheet music from Bach's Air on the G String, and it's back to barbed wire. It's a four second Vine video tweeted by Bethesda Softworks. What it means is for us to futilely wave speculation at, but we're suckers for a puzzle, so why don't we try?

Air on the G String comes from Bach's Orchestral Suite No. 3 in D major, and gets its name from the violin and piano arrangement by August Wilhelmj, a German child prodigy. You can actually hear Wilhelmj—or a violinist suspected to be him—play a different song via the medium of wax recording.

Air on the G String is Wilhelmj's claim to fame, and one of Bach's most famous works. If it all sounds very Fallout-ey, Bethesda Softworks VP of PR and Marketing Pete Hines says, "Guess again."

Alright, we will. If we take The Moonbeam Trio to be a nod to the 1930s and 1940s, Wolfenstein is a decent bet, but let's go even deeper. Air on the G String and the Moonbeam Trio have something in common: violins. Rearrange "Vine Violins" and you get "I involve sin," so clearly we're talking about Doo—wait, that's stretching too far, isn't it?

There's no way to know for sure what Bethesda is teasing, but conversation motivated by curiosity is fun, so we'll let you take it from here:
