I don't know...could consult the wishlist..or one of the already 1000 threads about this...
That's not what I asked. You aren't very helpful. You drank a large dose of haterade before you posted a reply. Very rude. It's amazing how rude people are nowadays.
I apologise on his behalf, but we do get a rather lot of these sorts of threads.
There is no simple answer to such a question, as GOG is rather secretive with what games are in the pipeline (for various good reasons).
Activision is now here though, and Sierra was merged into Activision a while back. That means there is a chance of these games arriving, we just don't know when that will be.
I certainly would buy them in a second if they did arrive, I'm a big sierra adventure game fan.
Here's hoping it's sooner rather than later, eh?
