I'm well, thanks for asking, mate.
I understand it's not just about cosmetics, but even for the fact that the theme is "more", it still makes me cautious. To me, PES 20 doesn't even need that much more. It needs addressing the concept of simplicity and logic in gameplay and definitely some night lighting for the pitch. For 2022, If they start from scratch, they'll understand to do less at the start. This way they don't create iterations of PES that have tactics and attack/defense mentality as their base gameplay, which has plagued the series since 2016.
The hope is that PES 2022 is completely different from PES 2020. However, the reason for my caution, and maybe lack of optimism, is that this is the same group that collectively decided to shackle the free flowing gameplay that PES was previously known for by over-complicating simple elements. Instead, they used a formula of: Player stats/ratings > Player Styles > Player Positions > Attack/Defense animations > Tactics > Advanced Instructions. All these elements affected the end result of gameplay. If they bring that same template into the next iteration, then I do hope they find another way around it or somehow, like you said, increase calculations and processes. I'm just not sure a new engine could save us from that base layer that has hurt PES for a while.
You are right though, we only have 2 games to choose from. It's good discussion, and nothing is set in stone. I've said it countless times over the years that I just want to be proven wrong. The first time was in PES 2020 actually when I was so surprised that they had finally fixed the DMF positioning. Let's hope they use resources to start from scratch and build the game the community deserves.
