The major studios are still using Maya, Photoshop, and other commercial software that doesn't work on Linux. They are using Linux for render farms and some custom software.
Maya/Houdini/Modo/etc run on Linux (this is what Weta, Disney, and Pixar do). Creative Cloud definitely does not, which is a bit of a problem.
This page seems to indicate that Maya is not compatible with Linux.
