I've gone back and updated my earlier Apocalypse Formations articles. Now that I have the book, I've updated the actual compositions of the Formations and I've now included the special rules that come with each Formation.

If you haven't caught it yet, I've also done a review of the Apocalypse 40k book itself, which also serves as a table of contents to my other, more detailed reviews on different sections like the Mission Special Rules, etc. Check that out here:
