I don’t know where to post this.
Based on how Dissidia Final Fantasy NT looks, it could be our expectation of how DOA6 will look. The game is beautiful in 60fps. The intro, win, and lose cut scenes are in 30fps though. Would love to see it all in 60fps glory.
If ever Tifa becomes a DLC character, and I think she’s like a DOA girl, I guess TN will recreate her beautifully.
And I wonder if TN will use DOAXVV-quality character models.
Dissidia uses a much more stylized art style than current DOA games, much more anime/Amano-inspired and way more colorful, so it will probably look stylistically quite different. In that regard Nioh, as mentioned by Brute, will probably come a lot closer to what DOA6 will end up looking like.
Looking at Dissidia we can hower get some ideas of what TN will be able to do on a technical level in DOA6.
Dissidia is a full 1080p resolution, 60fps 3D fighting game with 6 highly detailed character models on screen at once, inluding a highly detailed summon at times. There's always a screen filling firework of effects going on...
...and everything takes place on expansive stages, that often transform into a different versions mid-battle. This all in that quality on base PS4 is definitely impressive. Especially the character models:
While there are some not so great textures on the costume visible, the character model itself is of very high quality, especially polygon-wise. Each of those beard hairs is actually polygon modelled, not a texture.
What's also impressive: They managed to directly port the FFXV Noctis model into the game without any visible cutbacks. That model is made of 100k polygons, alone the hair is made up of 20k polygons, which is about as much as a male DOA5 character. Noctis basically wears DOA5 Bayman on his head.
(TN even got rid of the terrible hair dithering plaguing FFXV's hair.)
So it is actually possible to have high-polygon character models in 60pfs, 3D fighting games, and even 6 of them at the same time...
If DOA6 will just have 2 character models on screen, they can polish those up even more.
Regarding you specifically mentioning DOAXVV models: Compared to games like Tekken7 and Soul Calibur 6 they are of much higher quality already, but compared to what DOA6/TN could really do on PS4 that would be still a disappointment.
DOAXVV models are the same models used in DOAX3 on PS4 and apart from pumping more polygons in the girls' chests and butts, to make them look truly round, they are not a big upgrade of DOA5 models. They would have to recreate the character models fom the ground up to really give them that current gen quality. I lay my hopes in TN that they will actually do that.
