What makes you think so mate? I wish it's like you say as passing to an yearly subscription would probably be the nail on the coffin for me, but I guess there shouldn't be technical problems in deleting all the old files and installing you the ones with the supposed nw engine? Or is there something I'm overlooking?
First of all it is the pes developers first who have set this status. I remember 2018 and 2017, when major bugs were reported like the EPL transfer bug in ML and the developers said that such things can not change in a simple data pack and in the new game is needed to be addressed. I assume that when you can't fix a simple bug in your game modes with an update, it seems impossible that you can change your engine. Am i wrong on this?
There are many things that make me believe this. I mean I have seen big updates, but an update that changes so many core things, like game engine etc, i assume would be more of 50% of the data.
I mean a simple update 2021 seems bearable, but if needed to change so many things, to copy-paste, to delete data from your hard drive, in digital terms i things is unstable process and in real life terms maybe it touches zones of illegal, if it deletes data, it technically deletes our property.
Then it is the alltime derby phisical VS digital. If you want to have a full package retail with new engines, new gameplay animation etc, you go to the full release in order to exploit both sales, physical/digital.
If you stay in the update formula, you may exclude those who would buy a disk to play offline (without internet connection, yes they are minority but they do exist), those who would rent the game from a DVD club, those who would buy the dvd-BR-disc as collectors.
I mean only for the transition in engines.
To place it better, if i were Konami and I was told the plan-focus, that in 2022 we change engine and the future target focus is still to keep MC players buying coins from Lite or full game, I would do the same; 2021update, 2022 full release with new engine and then some future plan with yearly updates or Lite & premium Lite versions.
