Originally, this game worked for me in Linux, and in fact I played it for about 30 hours without a single crash, and the only minor issues i had, I'm finding, occur in the Windows version as well. However, at some point my sound drivers decided they hated Wine even more than usual. I've since reinstalled Windows (which hurt) and haven't had too much trouble.
But yeah, I'm looking forward to playing this game natively.
Personally, I doubt it will be anytime this year
