I think it might not happen this time, at least not as fast. M1 as the first ARM processor was in development at Apple for more than 4 years prior to initial release in 2020.
There were many rumors and hints Apple is working on a decent Intel alternative that will outperform it in each and every way. And well, when it was released it became obvious AMD and Intel have lost and have nothing comparable under their sleeve, M1 turned out to be better than anyone could ever think, Apple have outperformed themselves. And since they have made M1 so good, it became a solid base for newer models. Thus it might hold up well up until the M8 release
