Midoryu: There's a wishlist entry here, if you want to vote:
https://www.gog.com/wishlist/games/sniper_ghost_warrior_contracts_2 Here's also hoping they release the sequel here - finished the first game just two weeks ago.
On Steam there is a thread about a potential GOG release, which is ruled out at the moment, apparently:

hey there, at this time there are no plans to release SGW Contracts 2 on GOG, so if you'd like to pre-order SGW Contracts 2, Steam seems to be your best alternative. Wouldn't call that the "best alternative", let alone an alternative at all, thanks for sharing.
Continuing the waiting game then... and probably going for another playthrough of the first one too.
