In a situation like this, with a major directional shift, there are inevitably going to be far-along projects on the list of casualties. But I'd just say, as a rule, expect them to be things that perhaps haven't very publicly leaked that are now being very publicly anticipated. Or teased by section head producers and exec producers in interviews, for that matter. They're making changes, but they also obviously don't want to draw the ire of fans... and also, bluntly, anything that was on that Nvidia leak is now very old, which helps at least a little bit. But equally, there's projects that started later than those, which nevertheless were maybe only a little over a year from their intended release, that have been paused or canned as part of this.
Or to put it another way, regardless of which of those Nvidia games are real or not, be it all of them, none of them, or somewhere in between... none of them are on the list of projects that I know have been paused or discontinued. And people acting like FF7R-3 won't happen are also bonkers - what might happen is the scope of it might shift/change (up or down!) based on the performance of Rebirth... that's the limit. Unless the company is literally going under (it isn't; it just isn't performing with the efficiency and growing the way they & their shareholders would want) the big projects people think of as Square Enix's tentpoles are going to continue to come. They just want to find a way to make those arrive more quickly, and reach a wider audience. The things that might fall by the wayside a bit more are the more 'medium' size games. I posit that something like Type-0 or Stranger of Paradise wouldn't go through as easily under this new setup, for instance. It doesn't mean something like that would never happen, but the bar such a project would have to clear to be greenlit is probably higher now than it's been at any other time in Square Enix's history.
Capcom -- where they've focused down on a few key brands and really worked to make them regular as clockwork - really is the template for a lot of publishers rn. Mainly because Capcom has been mad successful. SE is trying to find a halfway house between that and what they've traditionally done, which is a very broad and eclectic range of content.
