I got all three figures from wave 3 a couple of days ago. The quality of the sculpts and paint on all 3 figures might be the highest of the lot so far. I think the level of articulation is adequate for each figure. I would have liked Azrael to be as articulated as Batman, though I understand that his bulky Suit of Sorrows makes this a tall order. He is a massive improvement over the Arkham City version however. Professor Pyg is excellent. His level of paint detailing is high, and his mask is a perfect fit. For me Man Bat was the stand out, as I've been wanting a figure of him for a very long time. He is taller than Batman, and has a 14 inch wingspan. I was pleasantly surprised, that he is bigger than I thought he would be. All in all, I would highly recommend all three.
Another figure I'd really like would be a Hush as Bruce Wayne. That way I would be able to actually have a Bruce Wayne figure, without having to buy that ridiculous Batman 5 pack.
I'm reeeeaaaalllllly hoping we see a Deluxe Killer Croc at Toyfair, around the same size as Clayface, and that we get to see Wave 5, as I only want Poison Ivy from Wave 4.
