I think the latest ruling on duplicate cards is "same pic, same name = same card".
Whether they have a special ability or not also (might) depends.
Was that ever resolved? If I remember right, Justin said you couldn't have a special ability card in the same deck as the same pic, same name, but no S.A. card, but Gabe said you could have three of the no-S.A. and one of the S.A.
And Chris told me this weekend that he thought you could have both, but only three total of one card.
