It's dumb. Same thing people said about SFV being SFIV with better textures 8 years ago. If it's not a radical stylistic departure, people will say dumb shit.
It's this. People need drastic stylistic changes just to recognize that something has been changed, otherwise they Berenstain Bears themselves into statements that just don't hold to any scrutiny. The version of Tekken 7 that people imagine when they compare it to Tekken 8 isn't a version that actually exists, same with SFIV and SFV.
