Thanks for the info. It's for the US. I know there are region lock issues other places, like Brazil and Russia. But everything I read indicates I'll be good for the States.

What region is this for? Just Europe, US, Canada, etc?

You will indeed be billed imediately :)

If I preorder, am I billed immediately or when the game is released? I'm subject to currency fluctuation so I'd prefer I'm billed immediately so I know what I'll end up paying.

Will the season pass be available for purchase as well?

Hello, The discount will last at least until the launch of the game, and yes it's a Steam key :)
