Honestly I think those that think playing as "origin" characters are going to offer anything other than a slight diviation from the plot will feel let down. If they use the same formula as DOS2 the origin characters will have few short side quests to resolve their "unique" personal paradigm. Astarian will kill vampire master, SH will deliver the McGuffin and regain memories to find "shocker" she was a brainwashed Salunite, Gale will get orb thing removed etc. etc. Maybe they will get a unique power or item upon completion. Bottom line is DOS is alien to D&D they are not compatable. It is a bit like comparing Disney to Manga, yes they are both animated but one is for babies the other is for grownups.
BG2 story was amazing, it didn't need hamstrung McGuffin story bummers like "the tadpole did it because we can't be arsed making a day/night cycle" or utterly unlikely floaty Gith box of destiny that does stuff because we cannot write cogent stories with 50 yearss of D&D lore to bounce off. It is amature almost like the new star wars movies, almost but nothing deserves that comparason, sorry Larian that was a cheap shot. It is the "This will never happen....until it does...dum dum dummmm!". Hey wouldn't it be cool if the main character gained superpowers for no apparent reason, motivation or effort....No not really.
DOS was original and fun to play but it didn't have 5 decades of lore history and evolution to consider when writing a story. Look what happened to CDPR with cyberpunk 2077. They went form the most trusted game dev in EVER! To the most villified in one game cycle. The same will happen to Larian if they turn BG into a cheezy DOS clone. Mark my words.
I don't think this will happen but we are not there yet. Try and cater to everyone and you please nobody. Pick a side.
