Normally a game spending years in EA is not a good sign. I'd guess development is not going smoothly.
We already knew that from Larian having to do mass hires everywhere and Swen saying their own developers weren't fully comfortable with programming the requisite changes on their engine in earlier PFH stream. Whenever the initial game launches, it will still be a buggy & broken mess.
To their credit, I have not encountered a single game breaking bug in Early Access as of Patch 6 and had only one crash to desktop for the whole playthrough. There were minor, mostly graphical bugs but nothing too bad or annoying.
P.S. It does not mean such bugs do not exist... it's just I have encountered none, which means they might not be too common.
