They started collecting apps Dec 01 and decisions were supposed to be announced Feb 01, but they extended the deadline and now no one will know until March 01. Either they didn't get as many applications as they thought they were going to get initially or they just didn't have time to process everything due to the holidays. My bet is the not as many apps as the cost per table went up and there are 3 different zone locations you can choose from w/the lowest being 1 table space (very very small) for an artist which is located way back in the back of the room where no one can see them. The other 2 zones are high end expensive location (which you see when you first walk into the Dealer's Room) and the next zone which is basically everything else.
I think the other problem they're facing is that Shore Leave (Star Trek) 36 is the exact same weekend (has been for 36-years) and a lot of people who attended both last year are going there this year as the costs for dealer setup is lower and its first come/first paid/first serve, easy parking/access, not to mention Otakon is the following weekend and Baltimore Comic Con is the 1st weekend in September. There were a lot of people posting last year after BronyCon that they wouldn't be attending the next one...so we'll see and I'm keeping my fingers crossed as this is how I'm not working a 'regular FT job' right now and this is how I make the extra money my family needs to live on/pay the bills.
You can always check the message boards and see if someone is looking to share a space, as if you only need 1 table and they only need 1 table, the space is definitely big enough to accommodate that.
