Does anyone know what all of SE's studios are doing?

Crystal Dynamics are completely separate from Eidos Montreal.

Don’t forget Crystal Northwest.

Crystal Dynamics are working on Avengers

Eidos are working on an unannounced game but there are ‘rumours’ posted on a number of gaming news websites which are correct if you want to do some google foo.

Crystal Northwest are supporting avengers for the time being but have some ideas they are testing out.

Avalanche are working on the inevitable despite it not being announced, I don’t think I even need to hint.

People Can Fly are working on Outriders

There is also the mobile devision and Square Enix London Studios, I have no idea what they are working on.

Dontnod are working on another LIS and have opened up a studio in Montreal and will possibly do work for Eidos Montreal

Square Enix Japan are working on a bunch of different things, a number of remakes and remasters, two new titles, publishing aside.
