They're pretty silent about modes, even possible online modes... I don't believe they found some free hours to build an ML.
More seriously
@H_G i believe it will be the same system than DreamTeam in training (which is, let's admit it, more advanced than every game they did before).
So i don't think stats will be different than they're already in the database, changing every players is a time loss + they already got a recyclable system to train players so... I'm 99.9% sure NO.
Now about transfers, i think it will be simplistic. I don't think there will be a "story" like on older PES.
Well i never been a fan of "movies" style, but more something written like in FM, or Career mode in older Fifa.
No idea if price will be related to transfermarkt, i don't think they are in Efootball so..
It was shitty in my opinion regarding player who get their values with their calculations mixed with players with a certain date TM value. No need that level of details to have fun : just price ressembling a bit to the real ones. I remember that TM value players where stronger but their price in comparison to any created or player without Transfermarkt were at least 1/3 or 1/4 less expensive for the same stats.
Also some rewards if you won X cup etc., with automatic save, to brought players. So people will brought player on ML to do the same on Dreamteam lol.
One thing that could, i said "could", make me try that game one day is an ML, but without regen. It will be hard to enter in that LSD casino world but at least giving a bit or money to try, when i see how much stuff which serves me to nothing i brought ftm...
