That's possible, but I think that in the end it's free money when they let GOG sell their old games. And there's always someone who will ask "if we can get $100k from selling our old IPs, why don't we?".

New companies in the catalog: Only By Midnight Ltd. and Maximum Games (release date: June 18) for Curved Space:

I guess I'm one of those weird ones. As, apart from Discworld, Ecstatica and the Divide By Zero games would be the ones I'm most interested about.

I wouldn't be surprised if that is not allowed (yet) by PlayStation Mobile. If the contracts are signed and they could mention the coming of the game to GOG they probablyt would.

I doubt that the publishers are the problem:
First of all, there is no such problem with competitors (Steam, EGS) - if a game is planned to be released in any of these stores, the information about it is almost always available and it is everywhere. And only with GOG suddenly for some reason there is this problem.
Secondly, even if it were true, the problem in GOG is massive: it's not just one or two publishers, but many publishers, both first time working with GOG and publishers who have been publishing their games here for years. That is, one could believe that this is a whim of Sony specifically, if the problem were not constant and widespread here.
Thirdly, the problem concerns not only new games - here are published games and 20-30 years old, which have already been available on Steam for years. It sounds unconvincing that their publisher insists that there is no release announcement exactly on GOG.

All in all, I concede that it may be a condition of the publishers in some cases, but given how often (almost always) it happens here, I think it's about the store itself.
On the main page there is such a funny (useless and always almost empty) tab - upcoming.
Is it really so useless because of the massive requirement of almost all publishers not to announce upcoming releases here or ... ?

Actually https://www.gog.com/games?page=1&sort=popularity&tab=coming is longer than what you see under the front page Upcoming tab. Why the tab only shows six items I've no idea, since the other tabs have more.

New company in the catalog: We Create Stuff, probably for In Sound Mind (releases on August 5th):

Days Gone is getting good reviews on Steam, so that seems like a positive if the game does show up.

Quote: In this video, I address my thoughts on the Days Gone PC port and provide details on controller and ultrawide support, PC optimizations, file size, and more. Days Gone releases on May 18th, 2021 on Steam, Epic Game Store, and GOG.....at a later date.

Saints Row: The Third Remastered confirmed to be coming to GOG on May 22:

Nice. Except for the fact they said Good Old Games instead of GOG. It's been like 9 years people.

Or as it's otherwise known: Project Spekulatius.

here ;)

Hush. I'm on a phone and at work. Lol

Wonder if they will offer a discount for those who already own the game here.
