Tonner had their duo of SDCC Exclusives on display: Arkham Asylum Joker (100 pieces) and Phantom Zone Supergirl (200 pieces). They were selling quickly, as I saw one woman alone rack up an $800 bill. I wouldn't expect the Joker to last through Saturday.
The rest of the display was made up of their DC Stars, Harry Potter, Tomb Raider and Pirates of the Caribbean lines. I'm very excited to see that Kreacher has a price point set. That must mean his really is approaching.
