I wouldn't mind random magical items if the unique ones all have fixed locations. I really hope they go wild with the magical items, since 5e severely lacks in this department.
I think there is certainly some ground to be given on the underwhelming loot and stinginess inherent in most 5e adventures. But that doesn't mean they have to "go wild" to address the issue. There should be some very fertile middle-ground between the DOS "super-loot" system and the 5e "we've-balanced-the-game-so-much-we-don't-want-to-break-it-with-a+3-weapon" system. You could, literally, give out 10 times as much loot as a typical 5e adventure path in BG3 and still be a small fraction of what DOS1/2 does.
So, in fairness, that's probably close to my number: Up to 10x the loot of a "normal" 5e Adventure Path. I think the integrity of the system can survive that in a video game adaption of 5e. Power is regulated by their Attunement system, and extra stuff just gets sold and can be converted into consumables and/or the occasional rare vendor loot.
Historically, I've been a very lean, low-magic DM for 30+ years. I could fill many pools with the tears of players lamenting their bare cupboards. But when I started playing 5e, I was astounded by how uninspiring (and anemic) most of the loot was. I fully expect Larian to put some more meat on that bone and I suggest that people who have a problem with that steel themselves for the coming bounty. It's a bit unrealistic to go into this game thinking otherwise. I believe that people should understand that the near constant flood of serotonin hits most gamers are used has to be a developer's concern.
Also, I would add that random loot charts in D&D is also a time-honored thing. If we're going to lobby for a legit D&D game, and they're going to carry the BG3 name, then we should be fair to Larian when they pursue core elements of the game. There are 8 pages of Random Magic Loot tables in the 5e DMG's guide. There is no reason they can't be using them (or a version thereof.) That isn't to say that every barrel, box, and basket should roll on those tables though... but the ideas of "randomness" *and* "fixed" magic distribution are foundational in every edition of D&D.
