Dont count on it . Season one got voice acting after the story was done in 0.9 . If this game follows the same number of updates we would get voice acting in 3 more updates.I hope the Devs will also add voice acting on the next update just like in season 1.
I for one dont like voice acting and think they are a waste of resources (the voices for the main cast dont seem believable to me and also are transmitted in a rough way sometimes). Would love a bigger budget on the music size (something like badik) or some new areas/events. But it is a feature that will be added and some people enjoy it. Those who dont have alsways the mute option available
