I was recently going through digitizing slides my father took when we lived in Nigeria in the mid ‘70s. One thing I noticed was the Kodachrome slides looked perfect—no color fading. Most of the Ektachrome and other E-6 type slides had significantly faded. They were mostly salvageable in Photoshop, but a lot of their color had gone.

Unfortunately Kodachrome will never come back like Ektachrome has. The development process was insanely complex compared to E-6 and it’s unlikely it would be cost effective for anyone to do it.
