Cant download yet also. I think it will be the same release like on steam. in 7 hours.
Ok, on Steam its availiable now but not here! Dont know why. I think, next time I will get my game there. Cant understand why it should be two different releases.
Because Steam gives devs direct access to the servers while GoG curates it through staff. On the up side this keeps a lot of the crap of the site, on the downside it usually takes a little while longer while they check the built.
