Great, that's nice to know! They were eager to distribute Driftmoon back in the summer, but their 3 year rule prevented it. Who knows, you might soon see Driftmoon on GOG!
Driftmoon is progressing well! A couple of months ago we decided to add plenty of polish and fine tuning to the current areas before progressing to the final areas, so we haven't had a chance to release the new monastery area yet. But it's coming soon, we have a deadline set for it!
After that it should be smooth sailing adding the last levels (Famous last words).
