In response to a direct question about the game coming to Linux, the developers said this:

About the game (From the Kickstarter)
Legends of Eisenwald is an original mix of RPG and strategy, with tactical turn based battles and a simple economic model. Rich possibilities of gameplay mechanics allow a player to feel being a hero of different stories ranging from treasure hunt to fighting for the throne. You can follow your game path as a Knight, Mystic or a Baroness and in each case gameplay and story will be partially different.
The game is currently in Early Access on Steam.
