No, because this is literally my favorite game series of all time. They decided they wanted to make a sequel. Which precludes any other sequel from being made by a different company if Larian screws it up.
Taking a look at the forums, people aren't that upset over the story, history, and atmosphere being displayed in the current game, Larian's inability to start a game not on a beach aside.
DoS also approximated the mechanics/gameplay of D&D. It's turn based, you have a limited set of stuff you can do, it's got spells, etc.
This wasn't advertised, discussed, nor promoted as a 'general role playing game'. Larian decided to take on the Baldur's Gate title. Which means they get to reap all of the benefits (a massive baked in amount of exposure and dedicated community who will buy the product), but they also shoulder the burden now of not just making the game they clearly wanted to make, which is DoS 3: D&D DLC.
These aren't house rule modifications. They are wholesale changes to the point where if you wrote down the rules of the game, you wouldn't recognize it as 5e besides some loosely named similar features. And Larian has the benefit of not even having to translate the rules to RTwP, making their job in terms of rules implementation an even easier task than Black Isle had to undertake.
I suppose the OP is right, I had expectations that the third game in a series would try to pay homage to the spirit of the first two games, rather than just being a studio produced mod of DoS.
