The game is out in Japan. Not yet for the US or Europe. From what I read its a fairly meh port with nothing enhanced for the pc (other than playing at higher resolutions). One thing I read was that the analog controls are reversed meaning that if you use a dual analog pad that the right stick would be the movement control with no way to change it in game. I also read about major slowdown problems with some who have high end pc's.
Ubisoft is publishing the Capcom titles so I hope they fix anything up but I kinda fear what may happen to the pc port of Resident Evil 4. Onimusha 3 was fine for the pc but it was just a simple port of the PS2 game right down to the controller symbols in game (y'know..X, circle, square and triangle). I hope Capcom puts some effort into RE4 because I own the PS2 version but would love to play it over in high res with some AA and AF to make it look even better.
