I don't understand why anything said in publicity mode could ever be taken as earnest. Of course Larian is going to say in interviews they loved BG and love DnD when they're making a DnD BG game.
Personally, I think Larian is the right team for the job simply because they're one of the biggest names making RPGs right now. Would I rather had some other company give it a try? Yes, I would. But I would also rathermost BG3 had been released in 2004 under the name the Black Dog and made by Black Isle. And we didn't get that either.
