The nice thing is that it is now possible to have a real choice between 5 great full frame cameras, 3 being Nikon, and 2 Canon. Though not a certainty, it seems pretty likely that Nikon will offer two FF 12MP cameras and two FF 24MP cameras within the next year. The other real benefit of the Nikon prosumer option like the D700 is that Nikon do not scimp on things like build quality, and autofocus modules in their cheaper cameras as Canon appear to do. Considering there were no Nikon choices just over a year ago that's a considerable improvement for us Nikon users. Yes Nikon has taken it's time, but their products have been pretty flawless once released, the same cannot be said for Canon with their 1DMkIII and possibly now this 'black-dot' thing with the 5DMkII. We'll see if the D3x excels in similar fashion, I suspect it will from the images I've seen.
The dxo tests at least demonstrate that Nikon's sensors are right up there with Canon's, and possibly marginally better.
An argument can be made that if for some reason you absolutely must have video now, and 21MP (17% less than Nikon's 24MP for what it's worth) then you have to buy a Canon 5DMkII, from every other perspective - speed, ISO sensitivity, autofocus, highest MP camera - Nikon appears to have the edge. I've only had my D700 in the water once, but I was pretty blown away by the available light high ISO performance which I think will impact my photography underwater a lot more than more MP or even video.
One has to be pretty jaded to be unhappy with any of the FF cameras presently available from either manufacturer.
On the second one I think the more reliable model is the D3 to D700 wait. Once the D3 was released, then just three months later we were all shocked that the sensor cropped up in a smaller body.
I think that the biggest caveat regarding a D700x is not the if or when. But I can see Nikon calling it a D900 and changing the body from the the D700 - much to the annoyance of those with D700 housings. I really hope that they don't, but there is not the same need to stick with a camera internal structure as with the D3 series (as we already saw with the D300 to D700).

I'm with you on this; it would seem logical that they do not change the body, as the only thing that has to change is the sensor; unlike the D300- D700 change which required a change in the pentaprism (as a result of the larger sensor) which is the biggest difference affecting the housings for these two cameras.
