BG3 is not a reskin of DOS2 its a D&D game wearing the skin of DOS2.
Do we really know if we can call it a D&D game? Not yet. There will inevitably be D & D5 rules that will be interpreted, rearranged or even ignored. I also look forward to being told exactly what it will be to comply with D & D5 rules for class, races, skills, attributes, feats, spells, abilities, fights and many other things. .
On the other hand, the general appearance of this BG3 is undeniably very (too!) close to DOS. In any case, I think that many players - especially those who knew the first BGs - expect something else from the Baldur's Gate license and from a truly D&D game.
And I also think Larian should take this very seriously.
