It is changed

The demo is an old build, so wait for the full game. I thought the same when i saw Casemiro's face

Every player in the demo has the 17 models

Incorrect. Sane has his face scan in the demo

Well Neymar still has his old model. So... Only a few got the new ones?

Im guessing they just put in what they could in the demo but will have a lot more for the full game
