Hey Blazin604, good to see you bro.  Hope the review will be soon.  Might be a while longer though, as rynomster (SDCDev) said he was in contact with Isidor, and Zeuner had requested some more documentation on the system. 

I saw on IRC, ryno said that Zeuner wanted something similar to this for Shadow: https://github.com/minium/Bitcoin-Spec

I guess it would help document things and make it easier to review.  Although the code is there for review, this extra documentation might make reviewing things a little more feasible I'm guessing.  Shadow does seem like a pretty complex and new system with a lot of code, so I'm guessing a review is no easy task.  I know a lot of people are hoping to see it soon, but I think it might take longer than people expect.

Anyways that is all the info I have on it, and I think nobody really knows when the full review will come out. I'm very interested to see how detailed it is going to be.
