I expect a lot of bitching about space assignments.
This year, I'm not sure we will see a lot of differences because of the relatively short time to plan. In coming years, I think it will be much more public friendly. I could see a 'fan fest' area with music, vendors, kids activities, corporate displays, public beer tents, etc. I also think that the corporate parties will split from the contest (you rent a site for the party in a separate area and don't have to turn in for the Open).
