The gameplay trailers and the improvements seen... 1-on-1, movement matching, ball physics, more animations etc. It will be *better*, but nowhere as good as it should have been. Other things like net physics have been monumentally downgraded, though.
Speaking about improvements from that gameplay trailer perspective and taking in count just those areas that you are mentioning, just some of them are slightly improved and there are others to those even worse:
1-on-1 - the balance that generates weight on the bodies of the defenders are too pushed back when players like Iniesta dribbles or Neymar does tricks, like some force is pushing those defenders back to lose the encounter (four steps in the wrong direction it's too much); we know that real footballers will not disconnect so much the duel, because they're focusing on the ball when they defend.
- there are encounters where the attacker is "skating" all over the place (noticeable without zoom in or slow motion too if you look directly on their boots), you can notice it more on Iniesta and Kubo on those personal encounters, like they are sliding combined with some floating movements on the field sometimes; it's like they're pushed to succeed on encounters with parts between frames unpolished/unfinished/rushed (less noticeable on Neymar's feints because it's captured from another angle).
- there should be a better collision system and physical contact between players that could lead to faults and penalties, and that's flawlessly missing.
- as a single positive aspect I just want to mention that's good to see players that are manipulaing the ball via dash, dribble or tricks, creating more space between the body and ball in certain situations.
movement matching - I guess you are refering on what they're calling "motion matching", but including the fact that will be just five tactical options in the "gameplan" plus advanced attacking/defending instructions where those options will be mostly automatic chained to those tactics, the positioning, anticipation and the structural awareness of the players will feel very similar between them, and you'll have a less diverse pattern that could affect also the motion matching, this I can't take it as some improvement knowing that this was existing in PES and was way better in previous titles before FOX engine, and I can give you as example PES 2013 with players having unique motion paterns depending the postioning on the field and stats of the players from the oposition (via Player ID, full control, proactive AI). If anybody can move like Iniesta in a certain direction that's PES 2014-2021 for me and not an improvement; could be something acceptable but not something that could be advertised in 3 seconds like some "new" type of motion matching system.
ball physics - can't see any improvement on that front either from watching the trailer, mostly because PES 2021 had it already good done related to the movement of the ball on the field. I would like instead to see how the ball reacts on deflections from different parts of the body when the ball touches a defender or when are duels between various players, speaking more about the upper part of the body as shoulders, head, even hands I would like to see a hand ball and penalties in this game that are related to those actions (at least in offline if they will ever release offline modes) and the ball reacting more natural involving its speed/direction/spin with the position and distance of the body. Don't know why they involved "some research institute" to it (that's of course a marketing lie if they can't credit the name of the institution in charge of it), because the ball movement on the field was mostly solid and without explaining what's better about it, I can't see it as a big innovation.
animations - again, there are different player movements in certain aspects that are encouraging to be watched (and should be normal that because it's a brand new game), but also are missing others that will be *available via future updates, so could be interpreted also as "one step forward and two steps back". In top of that there are parts in the trailer where those animations can offer some moments of fluidity, but others are feeling rushed/unpolished like in a cheap mobile game: feets skating, body slightly floating, parts that are not connecting between some frames; those overall can impact also first two points that you've mentioned above as improvements...
Overall, all those "improvements" are not really aspects improved (speaking just from the perspective of analyzing the trailer), and feels like this gameplay trailer was already stretched too much for what this game pretends to be. Judging the behavior of this company during their last few months about presenting eFootball, could be similar to a generic cheap comercial that is knocking on your door and then talking for two hours about how good it's his bottled water, but at the same time showing a bottle filled with air...
"eFootball Evolves Alongside the Community..." I can't elaborate more, that takes the cake...
