Nothing new here...below concept as old as the hills.
The usual rules apply: does the CPU/s exceed market requirements (cost, enhanced or extra functionality) significantly enough to yield a competitive advantage ?
If yes, market effectively and monitor buyer uptake (for both the end manufacturer and AMD).
That other old saying applies here, as always...you shouldn't place all your cards on the table at once. Keep that Zen2 option alive, no need to push out that product if things are progressing well with the current iteration. Rinse & repeat for Zen3/4 etc. Remember, Intel did this for waaay too long before Zen2 hit (no competition also allowed them to hit you hard in the pocket).
