Any news on when it is hitting gog?

BTW for those who lost their gear in NG+ keep your save from version 1.8; DO NOT overwrite your save and play the 300 mb hotfix from patch 1.10.

Nothing beyond that.

From reading that thread you linked, it seems its included in the file...
FREE DLC PROGRAM (16DLC) - 1.10 - 500mb
That is available on GOG.com.

Ah, well good then. Nothing to wait for. :D

Hopefully it fixed missing armor for people, but it didn't fix the retroactive fail for me. I also get 2 quests from Hearts of Stone upon loading my save lol! "Mysterious Passenger" and "Here Comes the Groom".

Happened to me too.

The only part of the expansion I could find is the world map of Velen. The new areas are already visible there, but if you try to go there, instead of the houses drawn on the map, there's just grass/nothing. So there was nothing actually added.

Well there was, because we are getting two quest logs for the expansion and having a retroactive fail of Novigrad City Closed part 2 all at the same time.
