Thanks to Mike for sending this in, it seems Man O' War: Corsair - Warhammer Naval Battles [Official Site] will gain a Linux version in future.
Mike asked them on twitter about it and got a nice reply:
@mikeonlinux that is the plan ;)— Man O' War (@ManOWar_Corsair) September 20, 2016
Looks like they changed their tune since April when they said no.
I must admit I hadn't heard about this one, but it looks like it could be pretty damn fun!
