With the new iPad being much warmer than the ipad 2, would putting it in a case or a body skin on it make it even hotter? Especially as you probably wouldn't notice the heat as much. And I would think both would trap heat in. I remember my wife had the original iPhone in one of those silicone cases (similar aluminum back as the iPads have now) and when she would watch YouTube for hours at a time I could actually smell the case burning. So she ended up taking the case off whenever she watched YouTube over an extended period.
