As I mentioned in the AB Sightings yesterday... my Sideswipe broke seconds after getting him out of the box:

Something to watch out for.
Also it appears every Megatron leg right ankle tilt is... broken? Like many reviews have shown, you can move the left one in and back OK, but for the right side you need a tiny screwdriver to pop the panel back properly.
