I'm kind of disappointed his moveset isn't TOTALLY original, but I bet that Sakurai felt bad about players who actually enjoyed playing Ganondorf, despite him being a clone. So it looks like they changed up some A moves, while keeping some too. I saw footage of the elbow Smash attack (I think it was forward smash if I remember correctly), as well as the Up attack where he does the lifted kick thing that Falcon does, but holds it for a while before it explodes. Best part of that one is now it actually sucks you towards it like a vacuum!
As for the B moves, in another thread it stated that while Up Special appears different, apparently he still has his Down Special, Wizard's Foot. Whether or not there are different properties involved I have yet to see. However, I feel that there are enough modifications to Ganondorf to make him enjoyable to play. Perhaps his Neutral Special or Forward Special are entirely different, or maybe Warlock Punch is chargeable or something, who knows.
