No, they don't count of course.

Edit: and what about EA games?

Since they're not technically released, probably not if they don't currently have a Linux build as they could be adding it later. However, if they do have a Linux build they obviously count.

Kingdom Come: Deliverance (typo)

The Fig list is short enough to go through:

https://www.fig.co/campaigns/deadfire

https://www.fig.co/campaigns/kingdoms-and-castles

https://www.fig.co/campaigns/make-sail (EA)

All released. Of course there are CJ and Phoenix Point in development, but that's too early for the list.

GoL posted the news that alpha/beta won't be on Linux, but is it likely to come?

Early Access only counts if they have already released a Linux version, otherwise we don't count it until release day.

Personally I would expect from such a page to present some form of gradation.
It's not ok to treat the same way Larian Studios, who ported Divinity: Original Sin after year and a half and they abandoned Linux while releasing second game and Obisidian who released all of their games with day one support.
