No. The two year transition was announced in June 2020. It doesn't start in November just because it took them that long to bring the first one to market.Over two years from when Apple announced that they were moving to Apple silicon in the near future. Sure. But since the transition started at the end of Nov 2020 we still have a bit to go before the two year deadline.
Regardless, they're not going to have an iMac Pro or a Mac Pro out by November. No matter how you slice it, they missed their self imposed deadline.
