If/when KF2 gets a Workshop it probably wont happen until the game gets full mod support. Only maps are supported right now. Hex is going away and I don't see TW supporting it by allowing that on the workshop after showing intent to disable it . The game still is EA and this is probably one of many things on the roadmap for full release. Considering Workshop one of the easiest ways for players to find and use mods for Steam games and TW has done it with the past 3 games, the odds are good for KF2.
