Wizard World (as in the parent company that evolved out of Wizard Magazine) has been having some money and management issues of late which is probably part of the reason why, but it's still the biggest con in the state.
But truthfully, I like the smaller cons. You don't get as many big names or panels but the guests they do get are more accessible and everything tends to be less cramped and crowded.
That said, I'm probably still going to WW this year anyway.
