It's extremely difficult to know how it's going to be as reviewers will not tell us due to obvious NDAs- any information would likely cause mass outrage amongst players as I can easily see people having their excessive overblown expectations/hype come crashing into a thousand pieces, as one way or another , one group will never be happy with how it goes, and that leads to cancelled sales.

I personally do not expect tav to get any additional content, and once I saw durge also have the dreams sequences in BG3 that largely confirmed it for me. I personally, am fine with origins as origin characters can still make decisions. You are just RPing as you would in any other game... most people are generally fine with this, we don't see people complain about being link, commander Shephard, Gerald etc. Just a matter of expectations
