CR has no control of DPR reviews, so we don't know the answer. However, the question has been asked many times on DPR, and the answer is always the same. They conduct testing after they get a camera to test, and spend a lot of time carefully testing it. It takes a very skilled person to conduct the test, and since they received the D800 first, it was done first. The 5D MK III will probably be ready in 2-3 weels or less, based on past timing.
CR does not yet have a dedicated professional camera tester / reviewer, and you may not see a review right away. They are changing the forum software to vbulletin, and that is a really big job to switch and to import all the posts to new software. The final result will be more and better features, but it might be a bit of a learning curve at first. I've played with the beta version a bit, it works well for a first rough cut, but there are issues with importing posts with images. There are only a couple of long time members able to try it at this point, so don't ask, I can't link anyone.
who cares? Is there something about the 5DmkIII that dpreview is going to find that nobody else has? are you going to decide to get one just be because of what they say?
It is the same as in the case of the D800. Everybody who wanted one already ordered and Dpreview said absolutely nothing new about that camera. The same will happen with the D5MKIII.
DPreview is so slow to come up with reviews that they are downright irrelevant at this point.

The June edition of What Digital Camera (interactive magazine) reviewed both the Mark III and the D800 and gave them equal scores of 92%. For what it's worth, they also reviewed the Sony A57 and gave it a 90%.
