wolfsite: If this collection is part of the Gold Master Series then there is a good chance of it showing up. However this Kollection will feature online multi player which other collections so that may be an issue if they are planning to just use Steam functions for Online.
Another issue would be that Digital Eclipse has been spotty here on GOG as the DLC and upgraded versions of Atari 50 have yet to be released and may never get released here for some reason.
The versions already here should be okay as these are the PC versions of the games and those don't seem to be included in the Kollection.
Best thing we can do is vote:

Almost all the games they are involved in if not all of them here they have dropped the ball in updating I hear that are laking updates that matter anyway.. as I don't have all of them and the ones I do have either was completely patched up before showing up here or was a case I didn't know they was a problem for Drm-free releasing for the most part .. Atari collection prime example ..
Granted I did buy the Tetris collection too but that's because I assumed in that case it'd no get any games added later because you know its a tetris collection didn't seem like there would be any added in a update or DLC and apparently if what I heard of a update is true then there was ones added in a update later and seems we have as far as I am aware we have yet to get it
