all i know is when i first saw this game back when they just had screenshots and saw the graphics it looked awesome, im sure if they go next gen it'll be on par
It's a shame they botched graphical power in favor of performance. Hopefully they won't screw up the aesthetics in DoA6 this way when they start working on the next gen consoles.
I'm sure that if Team Ninja decided to change the graphic was for a matter of general performances and loading times: one thing is a demo, another is a complete game. Should also be noted that the antialiasing is noticeable better in the retail demo.
However I agree that I would have preferred brighter colors like the ones in the alpha demo, but more toward the stages than for the characters' models.
