Another significant thing that has been spotted on another fansite that I missed.
They didn't mention the prize drawing on the Sunday for the free entry to the next BotCon... and it is one of the standard paragraphs that they recycle each year, so cutting it out is very significant.

At 3:15 pm on Sunday, we will draw for two free trips to the 2016 Convention from the registered guests who have completed their evaluations (airfare up to $450 along with lodging, transfers and package). You must be present in the Exhibit Hall to win!
If they were no longer doing the prize draw, it will be a very quiet end to the Sunday.
This year had very little on for Sunday, and a lot of people were only hanging around (sitting around the edges of the Dealer Room) because of the prize draw at 3.15pm.
Even most dealers were packing up an hour or two before the close because of the departure of most walk-ins and many pre-registered attendees, and if they didn't have the prize draw this year, the Dealer Room would have been empty after midday.
