Touch arcade also has screenshots of the new map that features magic defense tiles and barbed crystals.
Also some neat info that came up on the forums about some more of the unique mechanics of the team like:
no scrolls, but 4 haunches of meat that act like half potion, half scroll
they get 2 of the super unit, the chieftain
Their special is some sort of tornado move that can push/pull units a certain direction.
They don't get a helm, but their shield applies damage back at the attacker.
They also mentioned updating/fixing the various races, dwarves are getting buffed a bit, particularly regarding the gunner, paladin, pulverizer, and engineer (they haven't specified in what ways)
I think they've done a good job making the new race sound unique. I'm most curious about the particulars of everything most of all. The small details are just as interesting as the basic info.
