I agree with everything you said but to talk about Starfield, I think it even failed to be a Bethesda game. If their gimmick is to drop the ball, with Starfield they didn't even pick up the ball first to be able to drop it.
I'm not hopeful at all for TES6 and I'm a diehard TES fan, unless some major changes happen internally (and no, the engine is not the problem, it's who's developing in it and who's directing it all).
