For now the Rulebook is available in: English (printed and in the game box of course).
The French, Italian, German and Spanish are PDF only. (at least for now)
The translation of the entire game in the in the non english languages is in the works and we'll do our best to have a conclusion by the end of the campaign. We can't promise anything at this point, because it is not 100% depending on 2fat2fly Games.
But for sure we hope it will be done!
