I haven't found any detailed numbers yet...are there any official measures of how many fractions of a stop better the noise is than the 50D? It certainly looks somewhat improved.
I'd love to see it too. So far this 7D has most of the specifications from 60D. Not sure why they decided to change their numbering system. Doesn't make any sense! If you don't follow Canon's line it's maybe very confusing for those who just want to buy a camera and need a few choices.
As for ISO noise, they didn't go for 25K so maybe it was all left at the level of 50D. 50D noise performance was a failure and at ISO 1600-3200 didn't really deliver any better performance than my good ol' 40D.

The same DR before taking into account the reduced DR of the 5DII caused by pattern noise, or after taking that into account?
The pattern noise is included in the noise figures for the 5DII. If the 5DII didn't have pattern noise, it would have a little bit more DR, but it is very difficult to quantify it.
Just go over to DPreview and look at the samples posted in the 7D preview ... they look very similar to my 50D images. Take a close look at the 1600 images ... I'm not seeing anything to lead me believe that the camera is going to come close to my 5DII.
Sorry, but I didn't take the time to explain the difference between Dynamic Range and Signal/Noise Ratio. I can't explain every bit of signal processing and noise in every post with some technical aspects, but here is a good read:
And in "simple" English this means...
