I know the exact reason: GOG didn't respond to messages from the current publisher of the original Startopia and Urban Chaos when they tried to bring these games back last summer (at the time they brought both games back to Steam).
bluethief: This might be a situation like Urban Chaos and Startopia, where they were available on Steam and only came to GOG a few months later, for whatever reason.
I found out this situation and contacted GOG support for an explanation. After my ticket, GOG contacted My Little Planet Ltd and both games were returned to the GOG catalog.
If no one paid attention to this situation, I believe that both games would still not be available here.
As for Second Sight... It's now published by THQ Nordic who are extremely loyal to GOG, especially when it comes to old games. For example, they even allowed GOG to add unofficial Russian localization for Silver.
For some reason, I'm pretty sure that the reason for this delay is GOG and not THQ Nordic, but that's just my opinion.
