FYI, Major Bludd was originally scheduled to come out with wave 7 in March, 2008, but was held back until April, 2008 and released as the only foil carded figure in the wave 8 cases. He was later released on a comic card, I think in wave 9 cases. Wave 8 with Baroness, CC w/ MASS Device crystal, Roadblock, etc. was the first non-foiled wave.
As for the hand question, my vintage ARAH figure has only 3 fingers on his right hand (I'm looking at him right now). I think it's supposed to be a prosthetic hand and arm, as it has no articulation. I can't look at my either of my carded 25th figures, as I have them packed up right now.
