I don't think it's possible to accurately predict how the retro bubble will develop in the coming years as its market can be highly influenced by the silent ones who owns/license the IP for these objects.
For instance an analogy can be drawn here with analogue synthesizers, which were abandoned by their manufacturers yet eventually, thanks to a growing popularity in the last two decades, brought back to life first via software, then into simplified SoC, and very recently so-called 1:1 hardware replicas. A good example of this is the original Korg MS-20, made available again as a limited edition kit.
While the purist will find some differences between the original MS-20 and the very recent 1:1 replica kit, it was good enough to slow down, possibly stale and invert the price trend of the increasingly hard to find and maintain original hardware, and funnily enough, significantly increase the availability of the old synth, suddenly liberated by musicians who would see the added value of selling the old gear for a 99% as good, yet brand new, model.
Given circumstances in which retro gaming keeps on increasing in popularity, I do not see far fetch the idea of a manufacturer, the original IP owner, or a licensed one, starting to make 1:1 replica of old console hardware and games.
