While platforms have yet to be confirmed, it's probably safe to say Feral Interactive will likely be porting Life Is Strange 2 to Linux.
We already have the original and Feral Interactive are currently porting Life is Strange: Before the Storm to Linux, although it's suffering from a delay.
Anyway, here's the teaser:
Given the date in the teaser, it seems this could be taking place three years after the original, so who knows how things have changed. It appears Max isn't the only one with some kind of super power, as shortly after the officer asks for backup we see what looks like a display of supernatural force blasting from the right, sending the officer and the car rolling.
Exciting! Can't wait to see more when they reveal it properly on August 20th. Episode 1 of Life is Strange 2 will release on September 27th 2018, so it's likely quite a while before we know about Linux support since it's usually talked about much later. I would say a Linux version is more likely when all the episodes are out, however it would be great to see support much earlier this time as spoilers are hard to ignore for such games when they're released.
