Thank you for someone finally using the fucking spoiler tags.
Kinda pointless since its from a public trailer, don't you think? Then again, I never spoiled anything...

HOLY SH*T, THERE'S POSSIBLY MORE MOTHER BRAINS!?
Kinda makes it seem that Mother Brain was an Aurora Computer that either became "too smart" and went rogue or was taken by the Space Pirates and adapted for their use, but it in turn ended up becoming too powerful and took control of them instead.

Hence the "retcon" part of my post.
The original story was that Mother Brain was an organic supercomputer created by the Chozo for the sole purpose of overseeing their breeding program of Metroids needed to combat the X (Retro referenced this when they said the Aurora units were given gender identity in accordance to their designated purpose - Mother Brain is the "mother" of the Metroids on Zebes, and hence female) Now, according to the video the first Aurora was created 20 years ago, and previous canon says this was about the same time when the Space Pirates first invaded Zebes. Coincidence? Metroid Fusion's portrayal of the Federation says no. It is a retcon either way, but it is in fact quite possible someone in the Federation is the Space Pirate "High Command" mentioned in the Prime games. If true, this would indeed explain quite a bit.
As for Corruption, Nintendo long ago revealed that a Phazon virus had infected the Federation computer network. We now know exactly what that means, with thousands of Auroras under the control of Dark Samus. I'm guessing this will play into the story quite a bit.
And that last image shows an exact replica of Tourian, with Mother Brain in place. Presumably you fight her as a boss, though Retro might also use this opportunity to explain her return in Super Metroid. The other Auroras are likely clones of the original Mother Brain (similar to how the Metroids in Fusion are clones of the Hatchling) so technically she could appear in any game after this.
