One thing that I like about the Tekken 8 trailers is that the characters feel more unique both in pre-battle cutscenes, the attacks they are able to perform and the rage arts. Asuka might be the best example to that since she seems to have a more personal spin of the fighting style that she's been using up until now that goes very well with her personality, which Tekken 7 wasn't able to achieve/emulate too well imo.
