Also, Larian has so much work to do on the fundamentals (UI, controls, writing of Act 1, game mechanisms, etc) that I don't see much value for them in releasing more content (Acts, races, classes).
I very much agree that they should prioritize working on the fundamentals, but I think for the most part underlying mechanics and additional classes/races/companions (acts will only come with full release) don't clash. They're likely done by different people and introducing a new race doesn't impact working on the mechanics, imo. And those new things need to be tested as well; we have 6 classes left! And quite a lot of subclasses. And some of them have non-straightforward mechanics. Even if we get one class every two months, it will take a year. That's a lot of testing needed. Another thing is that the sooner those new elements get implemented, the sooner we can test how they work with the revamped systems; that's important too.
