Alright, I guess GOG's forum doesn't like too much text in one place. I'll continue here and link to this in the first post.
Soldier Of Fortune 1 & 2 - Activision I thought maybe we'd be seeing this appear as one of the Instagram'd hints - "action game full of gore" but somebody suggested this would probably never see a re-release as there were issues with the magazine of the same name. An aside: "A MMOFPS based on the series, Soldier of Fortune Online was published in Korea by Dragonfly and went in Closed Beta on August 12, 2010 and ended on August 16, 2010" - Wikipedia
Call of Cthulhu: Shadow of the Comet & Prisoner Of Ice - Infogrames/Atari I'm guessing maybe there's some trademark problem, maybe a license to use the word "Cthulhu" that expired. Or maybe 2K owns the rights to the phrase "Call of Cthulhu" a la Dark Corners? As IAmSinistar suggests below, it appears Chaosium -
http://www.chaosium.com/index.php - has the rights to the phrase "Call of Cthulu", as "they are the originators of the role-playing game of that name." According to
http://lovecraft.wikia.com/wiki/Copyright_status_of_works_by_H._P._Lovecraft, "Chaosium, publishers of the Call of Cthulhu role-playing game, have a trademark on several Lovecraftian phrases and creations, including 'The
Call of Cthulhu', for use in game products."
The Sims Complete Collection - EA Of course, bricks will be shat if this is released, and I assume EA wants to focus people's attention on Origin for Sims games. $20 seems like a good price for everything [assuming all 7 expansion packs have substantial content], although used physical copies are going for 12 bucks on Amazon.
Albion - Ubisoft Blue Byte Oh GOG, where is this game?
Heart of Darkness - Infogrames/Atari (Europe) and Interplay (NA) It's possible having two publishers is the cause of the problem, or it may be compatibility issues. More research is probably needed.
Deus Ex: Human Revolution - Squeenix It's possible, in a year or so, Squeenix might be willing to release an openly DRM-free version, assuming SteamWorks wasn't worked into the release from the beginning.
Sid Meier's SimGolf - EA Since we so both Firaxis and EA appear together a la Alpha Centauri, I assume this can show up unless compatibility issues are holding it back.
Dark Messiah of Might and Magic - Ubisoft I'd assume we could see this show up once GOG has brought a fresh "batch" of Ubisoft games.
Swat 4: Gold Edition - Vivendi/Activision Oregon Trail - Gameloft/Ubisoft Depending on what the rights' situation fully looks like, if Ubisoft does have the rights to the Broderbund/TLC versions of the Oregon Trails, it's possible we could see re-releases here if GOG views them as more than "edutainment" and can get them working.
Sim City (original) - EA Probably little point in releasing this if 2000 is here (coupled with the release of the source code already), but it might be nice to at least have this for the people who want to buy it. Maybe it could come as a freebie or simply be added on to the Simcity 2000 package for free.
Emperor: Rise Of The Middle Kingdom - Activision The last of the great Impressions builders games, I believe. Kevick the Frog (what's that GOGlodyte's name?) will be happy when it shows up.
The Walking Dead (Episodes) - TellTale Games Perhaps TellTale is uneasy about openly DRM-free for such new games?
