Piling on the speculation, the dynamic power draw when raytracing was enabled, especially the memory access patterns - and the poor performance in spite of the increased power draw - might have been the final blow. But if an entire h/w project is punted to "the next release" there's more than just one feature that contributed. So maybe the halo feature, raytracing, plus the other new Metal 3 features all contributed?
