Been playing the demo and it's simply amazing! The graphics are really good, except for some nasty textures here and there, especially on the blood.
The music sets the mood really well and gives each a room a creepy and scary factor.
The 3D depth is very nice and you can set yourself to Normal, Strong or Very Strong. I'd set it to Very Strong if you want to see Jill's wonderfully crafted rear. ;)
However, there are some weird things going on... for one, when your knifing upwards to the ceiling, it looks like your top body has split off your butt.
But it's really nice and could well be one of the 3DS' 2012 hits.
