The thing is, i'm standalone now. I don't want to work for any team as an editor, no more "release date" or pressure. Or problem because X persons left the team during the process. I don't know what others teams will do, personnally i will edit to make 20-21 "perfect" season, and play. That's all, but you may found others teams that will updates stuffs. Continuing or not will depends on Efootball quality (if it's as PES 2021 > OK, i don't care as long as data is updated, i'm a database man lol) as there's an edit mode.
But look at all the leagues and players in PES 2021, it's just completely crazy to update fully a database. Create youth signed to A team, Create new players from nowhere never been IG before, update stats, remove and assign players with transfers, create and apply new kits for the WHOLE database not only England 1/2 and Spain 1/2, but all Swiss, Turkey, Russia, Belgium... And on PS4 you can't remove licenced kits so...) etc.
So it's a no to me, completely crazy to do that you need at least 10-15 people (more or less the editing team in PES just for stats, and 10-15 others for faces). I know one Editor = 4 teams to handle. Now there's rank, and some correct the whole database : my partner was doing it for Serie A and B.
If i create for example the promoted teams : it will be 20-21 rosters. No new kits, the less i can. I don't even know, to me 2021 should still 2020-21 season, except on PC mods.
The thing is i'm not on PC and impossible to play on my big 4K with a PC, i'm more a console player. PC retro, i switch to my 81cm Samsung (enough) but on my 19" screen if i remember the size... Well it's not immersive, too small. You won't see me on PC editing, but i may help with some stuffs sharing for others editors.
Well now about your expectations (21-22 on PES 2021), perhaps one or two guys on future PESunivere will do transfers, and some creations for important player (be carefull because creating... Well there's no one involved as i was), but i know they were working on 21-22 transfers for PES 2021. Or the guys given up, i think he/they understood how exhausting mentally it's to edit a full database, even without creating. Even if just doing transfers is far less hard than creating players from scratch, if you do it good of course : you can just, like some teams, put the name, change height, weight, age skin color, sometimes random stats for having a not too high overalll and Voila! That's what i call fast-food editing, there's plenty of those guys on Youtube. Kits, names and Emblems gives you the illusion you're playing the real thing if you didn't checked about the team, players likeness, strenghts, and appearences. But you won't. Illusion, randomness.
My work, was all created Bundes, Other Euro, MLS (that i didn't wanted > MX is 10 times easier to update), Libertadores 2020, J-League, AFC duplicates, All Euro players to replace (duplicated with DLC 5.0, then 7.0). I was on everything, updated everything until last day of june. For what? Nothing. Not a thanks lol except for my close friends who helped me, but still asked after if i will update to summer transfers lol, after litterally let's say 6 months of editing lol, with not even a guy to assign some kits. And every player was worked like if i got to reproduce a real person : for some players i even checked vids on YT and tooks notes. For Overall as they're important in PES process of keeping the balance, i used TM market value and compare with IG players (of course, sharing likeness, nationality etc.) And used FM, sometimes FIFA for youth with my own "formulaes" if i may call them like that. Unfortunately it takes times, and i could'n't do it for every teams and players. But stats were updated, as MLS gotted end 2019 stats.
I think you may found some 21-22 season but not so soon. Editemos PES yes. Perhaps Virtuared probably, there's others teams you know. Just wait a bit for the transfers window to be closed and you will get what you want mate, but i repeat : FTM it's too soon.
