IGN went out and collected a multitude of screenshots focused on these new armor sets. As we know from this morning's New York Times article, the sets will be 9 pieces (all of the usual armor slots as well as one ring). The pictures are somewhat blurry, but the print is legible and the visual concept of the sets are obvious. The armor show seems to follow the recent trend (with Dungeon 2 sets) of more subdued armor coloration (no bright purples here), which I'm perfectly content with.
Update: Of course as soon as I posted that, I found some additional information (better organized, if nothing else) here.
