Isn't Kinect 1 not already capable of 640x480 depth resolution on the pc? I though it was quartered because on the limited bandwidth on the 360s USB interface?
Going from 320x240 to 512x424 won't do much with the wider field of view.
320 over 57 degrees is 5.6 pixels per degree, 512 over 70 degrees is 7.3 pixels per degree, a 30% increase in resolution at the same distance, that's not going to resolve fingers reliably.
