At some point, when you're consistently unhappy with ~10 million sales, you might want to rethink your resource expenditure.
Like I feel most of the problems people are diagnosing aren't really that much of a problem. The direction doesn't appeal to me personally, I'd prefer a more whimsical tone and a more stat-driven combat system (doesn't necessarily have to be turn-based). If I had a PS5 I might pick it up after a price drop though it's not a must-have. Still, I think people are sort of just using this as an opportunity to project that their preferred direction for the series would sell better which we can't truly know.
Even the issue of character action combat being niche doesn't quite hold up. Everything I've seen about the combat doesn't look anywhere near as complex as DMC nor does it seem to require as much precision. It's fairly grounded similar to FF7R, you don't seem to be juggling enemies around in the air through a complex chain of various actions.
It might not be TotK or sell 20 million, and it's not my cup of tea and might not be yours either, but it's going to be huge regardless. Obviously, this is a major release and there's an audience for the direction it's taking. To me, the fact that SE would still be unsatisfied with that just is more evidence of how unsustainable triple A development is if ~10 million sales provide an unsatisfying profit compared to the budget. Not that it's all their fault; a large chunk of the audience has unrealistic expectations just looking at all the "it looks like a PS4 game" talk regarding the new spiderman reveal.
