I don't know, my gut is telling me we're getting a veteran's special moves.
Now that you mention it, the only special moves updates possible right now (i.e. barring a newcomer being revealed) all belong to veterans...
Edit: On the bright side, most of them haven't significantly changed from what we know, so I'd kind of call them unlikely to get updates. Kirby's hammer changed a bit, but that's probably all. I can't remember if Pikachu was playable at E For All, but can't see much change there either. Nobody said Samus changed. Bowser just has a different forward B. (Then again, Mario only has a different down B and he got his update... ) Can't imagine DK changing. Yoshi's eggs work differently. Peach's forward B works differently but that's it. Ice Climbers, who knows.
I think Zelda's probably the one we all want to see. Even if Sakurai doesn't say a thing about her down B, I'm at least curious enough whether they kept the OoT-themed set of Din's Fire (which sucked anyway), Nayru's Love (which also sucked), and Farore's Wind (awesome).
