YES,
If you hop on over to the official site there's a Linux "tux" icon to show it will support Linux and the press release sent out by 1C Entertainment has also confirmed this.

si vous vous rendez sur le site officiel, une icône Linux "tux" indique qu'il supportera Linux. et le communiqué de presse envoyé par 1C Entertainment l'a également confirmé.

Thanks, that just raised my interest in the game by 200%. :-)
I just hope we'll see the Linux version here on gog, too. Sometimes Linux versions just get released on Steam, for whatever reasons...

Your answer and a great reward for me, I put this message just for you. ;-)
