I've posted a review. See it for some information about the set contents.
WotC has clearly already benefitted from the lessons WizKids has learned doing Pathfinder minis. The smaller minis are separately bagged and tucked into the hollows of the plastic shell holding the large minis. Between that and the separate bases and posts for flying minis, I had no damaged minis in my case of this set, and no bad paints either.
A comment for Paizo - the lower MSRP for each booster means my local FLGS is willing to stock these on speculation - and they're selling rapidly - where he can't stock the Pathfinder boosters because people in my area just won't buy a booster at that price point.
Paizo should examine this set and have some serious talks with WizKids about options for quality improvement. Both the separate-flying-bases, and the fewer paint steps (and resulting reduction in paint-step-related flaws).
