Halo Fest guests

I am sure Karen Traviss and Greg Bear will be attending but I was wondering if Eric Nylund or any other authors from the Halo universe would be attending. Would love to have some of my books etc signed. Also have they made any announcements of who from 343i will be there or if any Bungie employees will make an appearance. I know Bungie is done with Halo but they are only a short drive away.
