It was an awkward time because iirc they were all developing their next gen shit like Saturn, "Ultra 64" etc, so there wasn't much point in going all in on 32X/CD or SuperFX.
My timeline might be off a bit since I don't know their exact R and D cycle, but I bought a Saturn, and by the time I got it on the first day here it had been out in Japan for at least a year.
And the Killer Instinct arcade was out for a long time and advertised "Ultra 64" coming soon, year(s) before N64 came out.
