Well, well, lookie what I found here: http://api.gog.com/products?ids=1113697773

Seems to be an entry for the "Deserts of Kharak Khaaneph Fleet Pack" DLC. Steam link for reference.

Cool. Hope we will see it soon.

Although it makes an interesting lead, I wouldn't get my hopes up. We can look at TES IV: Oblivion for example: we learned it has an API entry (or at least we knew it did, before GOG started hiding some of the entries returned by the APIs) more than a year ago... and it still hasn't been released.

On the other hand, SCPM discovered an entry for Homeworld Remastered and it did get released.

i am so fragile from the oblivion

I still haven't seen the base game show up, but I found an entry for yet another "Deserts of Kharak" DLC : http://api.gog.com/products?ids=1177623749 . Let's keep our fingers crossed.

Not sure if anyone is interested in hearing this, but I also found an entry for Stranded Deep: http://api.gog.com/products?ids=1223720500 (edit: seems like someone previously found a support link for it, so count this only as a confirmation please).

If I find anything else, I'll add it to this post from now on to avoid cluttering up the thread.

Update:
* Found one more "Homeworld: Deserts of Kharak" DLC: http://api.gog.com/products?ids=1387822985

Excellent news! Hope we backers can get GOG keys as soon as it arrives here.

Updated list on this page

Well, we know the blues are watching at least :): the ids I've previously shared for the "Homeworld: Deserts of Kharak" DLCs are no longer returning anything.

Here are some new things for them to hide/remove (if you come at a time when these are already blank, you'll have to take my word for it that they were not at the time of posting) - note that most, if not all, of these are already collected by Andrey82, based on SCPM's listings:

I have yet more data to sift though, but I'll be back later. Again, this doesn't necessarily mean we'll see the games released, but simply that GOG has (yet not hidden) entries for them, which can mean one of many things.

Still, it's interesting to see what's out there, right? :) Cheers.

Just for history (independent confirmation):
At the time of writing my post, ALL links above work and point to the corresponding games (APIs).

P.S. I added this message because with SCPM's list at one time there were many questions (by those who tried to open them much later) that links in it do not work.

Guys you are amazing :)

That's pretty consistent with SCPM's list from last year. Good omens, maybe?

I don't remember this being singled out by anyone before, so I guess it's something new for the list - Hellblade: Senua's Sacrifice: http://api.gog.com/products?ids=1573355755
