HunchBluntley: Unannounced as in "not explicitly mentioned in a news post".
Gydion: I thought it was a forum news post or are real news posts under
https://www.gog.com/news/? Also, "technically".
Eh, it's just my definition for these types of things. kbnrylaec's reckoning on the matter might well be different. But
a post in a thread is nowhere near as visible as
the OP in a news article's comment thread (or any other stickied post), which appears at the top of every page.
My personal rule of thumb [EDIT: for the purposes of these tracking threads, that is] is: "mentioned in front page news article ( = mentioned in OP of forum comment thread) = announced; only mentioned in forum comment post, or only appearing in one of the tabs on the lower right of the front page, etc. = unannounced".
