I don't see how it'd fit with the traditional pricing, but someone an DPR said that Nikon USA was targeting the D700x to be the same price point as the D700. That's interesting to me because at that point you'd basically be paying a premium for high-ISO, high-speed shooting, or getting a discount for higher low-ISO IQ. Sensor cost is basically driven by physical size, so I'm almost sure the economics would actually work out ok- but that'd mean Nikon not maximizing per-unit profits, but instead going for volume. With the more accurate focusing module from the D3x, that'd potentially make Canon's choice to re-use the 5D mk I module a bad choice.  1DsmkII folks who've played with the D3x have said focusing accuracy is better, the 5DII is bested by the 1Ds bodies as near as I can tell.
