I was there but I didn't buy anything. Speaking strictly about geckos, every table seemed to have the same thing: leopards and cresteds. Only one table really had a different, unique species of gecko. I brought a wad of cash with me just in case but I didn't see anything new.
But I will say this: if I stop at your table and I'm the only one there, say hi or make eye contact or something. Some vendors ignored me and sat twiddling their thumbs. This was at about 9:30 so I know they couldn't have been too tired or bored. Anyway, it made me feel uncomfortable so I just moved along.
