Can somebody confirm this game is coming to GOG? I have been holding off on getting it on STeam because I keep reading it is coming to GOG,but it has been two months since it debuted on STeam,and has not shown up on GOG. Can someone confirm it will be on GOG?

I've heard there's a large back catalog of games that GoG is releasing a few at a time. It could just be a matter of time getting here.

The most recent information shared on http://www.gog.com/forum/general/games_that_are_unofficially_confirmed_for_release_in_the_future_part_2?search=lethis was 'We're working on this and are currently in contact with GOG. However it appears that the game will be first available on Steam.' That was back in May.

Bumping because of new relevant info.
