I can't imagine them doing it any other way; one can hope, though, that they strive to make it even more interconnected, so that you don't wind up with areas like Tomb of the Giants that have only one entrance. All within reason, of course; I wouldn't want them to be connected just for the sake of being connected. The organic nature of the layout of Lordran was such a massive aspect of why it worked so well in the first place.
Hopefully they just leave out shit like Tomb of the Giants alltogether this time
