Exactly.
A delay to PES 2022 was always highly possible, assuming it's all new, even without the pandemic. So I'd say that the chances of a delay now, are fairly high, taking everything into consideration.
Add to that the reduced user base on next-gen consoles, and Konami might well prefer to delay anyway, with the bonus of avoiding another half-baked game.
But economics will decide things, and I agree that another season update is on the cards for all, with PES 2022 being released really late in 2021 at best, and more likely in 2022.
How Konami dress all that up is anyone's guess, but I agree that most people would understand, and prefer it that way in the long run.
