It won't drop out of the sky for you, unless it should. But since you're replying in this topic, I'm assuming you were a kickstarter backer and hence have a larian vault account. In that case, I understand that you should be able to get that via the vault now.
Now, actually getting it on GOG has its own issues. I know GOG usually comes with a delay with the release of every title, patch, etc. But I understand that there are some other GOG issues... from GOG... at the moment.
