Yes, the 10 or 11 levels "Lair Beneath Phantom Forest" doesn't exist and the "Henchmen becomes Companions" goals is rather a joke, as there are only two companions upon release and they have very limited personality and interaction. They are much more like the extremely limited one-dimensional NPCs from Baldur's Gate I and other CRPGs from the 80's and 90's that had NPCs with a few lines of dialogue and perhaps an optional quest than the Baldur's Gate II/Planescape:Torment NPCs that set the industry standard by making the standard RPG party feel like a party of bickering individualists with depth to their personalities.
Larian, faced with having underestimated the work involved in getting everything they'd promised done to their desired level of quality, being a sensible company chose to allocate their resources differently from what they'd promised in the kickstarter rather than trying to achieve everything on the same budget and ending up with an inferior product.
It is a hard call to make, but that's what game development is all about. If you don't know how to triage, you have no business leading a game development project.
Some of it will probably come later, some not at all.
They'll hopefully keep the experience in mind should they start another kickstarter and be a bit more careful about what they announce as stretch goals. While it is common to underestimate budgets and perfectly understandable that they triage, those whose particular bits of interest gets the cut at the cost of something else are understandably annoyed.
So my suggestion is that you look at the finished product and ask yourself if it is worth the money you threw into the kickstarter rather than worrying too much about what might have been - after all, projects on kickstarter isn't a preorder business of buying a feature-list - it is much more like dealing with a lobbying/political organization:
You are interested in some of what they promise; They are interested in your money and in delivering as much of what they promise as they can manage, in the hope that you'll throw money at them again once you see what they accomplish. Both sides know that there are no guarantees.
If you don't feel it is worth it, or feel that kickstarter promises should be honoured regardless of costs, don't throw money at any future development project they might kickstart.
