They seem to be enjoying this aura of mystery and these big, high-production value reveals. As someone who works in a creative agency, this is a bad way to collaborate. The client (in this case us, the EA ‘backers’) either feels like they’re settling for something not quite what they asked for or the studio has to do a lot of extra work to bring it in line. Communicating effectively can avoid all of this.
Early Access doesn't mean made-to-order, and even if it did not all players want the same things. The responsibility for creating a fun game with effectively inter-locking systems is Larian's. Designing to specs laid down by the noisiest players doesn't seem like a good idea to me.
