Don't bite off more than you can chew with the sequel, or you're just going to repeat history. I liked the game since launch, but it was still very evident CDPR wanted to do more than they realistically could while still actually releasing a product.
Great vision, perhaps too much; but poorly managed their time and resources. Stretched too thin on portability to every available console at the time of release. Constant changes of scope. Etc.
Just do like Baldur's Gate and release a portion as early access, then release the full game on all platforms when it's ready. Ideally skip early access and just release when it's actually ready, but the early access option is acceptable.
Honestly part of the benefit of early access is the diverse hardware and diverse playstyles being tested. I'm sure part of BG3's success was due to them taking feedback and bug reports from the early access players that submitted things and implementing the fixes and changes based on customer feedback. It definitely gives unique insight for the developers while the game is still being made.
