I think the upcoming patches doesn't bring us new content. They "fixed" (in big quotation marks) Karlach and Minthara, which were both the biggest threads on forums, so now they will mainly resolve bugs and as we all hope do DE in the meantime. If they fix all the major issues mentioned in previous comments + if they add their own ideas and improvements, we can expect quite different game experience in DE.
Also, it looks like they haven't fixed Minthy at all, I haven't tried it myself (all playthroughs are on hold until Karlach gets what she truly deserves) but a lot of people say that there are literally no changes to Minthara dialogues. Damn, I wish there was more transparency but it feels that all latest posts from Larian are a bit sketchy.
