To my understanding, games which require FW 19.0 or higher simply won't work on the emulators.
Why wouldn't they ?
Considering the work that was put in Yuzu and Ryujinx and how both (but Ryujinx a bit more) were able to run many games day one without too much work, I have no doubt that these will run.
It's the end of the Switch's lifespan, there aren't that many big releases to come before the Switch 2, at least I can't think of any despite Metroid Prime 4, and this one is definitely going to be emulated.
Remember when Smash Bros got leaked ? The intro movie couldn't be run by the emulator and because Yuzu and Ryujinx wouldn't work 2 weeks ahead of its release, people had to rely on mods to disable the film to play.
Not only that, but even tho forks do exist right now but with very little steam, it's pretty much a given that when a big release will come, people will jump back to them (I expect Suyu to get at least a little hype when there will be some releases that current ryujinx/yuzu builds can't run)
Maybe I'm wrong because you know ... can't predict the future. It's just normal that things are now much more tame, but that doesn't necessarily mean that it's not bound to get better.
It's never going to be « revived » to be as healthy as it was before tho. But this death was bound to happen anyway.
