I still think they'll need to think about delivering on that 10 level dungeon later on.
IIRC, there won't be a big dungeon - they decided to break it down into many smaller ones which are already in the game.
It's my understanding that GoG themselves chose to delay the release, not Larian.
I'm aware of both of those circumstances but that doesn't change anything from my perspective. They need to ensure that kind of mixup with GOG never happens again and they need to think about bringing the 10 level dungeon as an expansion later on. The game has been quite successful, it has dominated Steam and GOG for a month and they plan to support the game with content long-term anyway so I don't see why as part of that content they wouldn't bring something they promised in the first place.
