As dagger stated, not ALL of the SnF (and to some extent, MotW, DotF, & T&B) material have been included in CW. Makes me wonder if they should have made it a $30-$35 supplement (bigger, more pages, etc.), rather than $27. It's a rather thin hardcover book, along the same line as A&EG.
I suggest you find it in stores like Borders (where you can actually sit down and read) and take a look at it yourself.
