Whats all coming out at GenCon

What all books are being sold at GenCon besides A Call to Arms? I was told by a friend that the Psi Corp book is going to be sold there. So can someone give me some insight on this?
I cannot comment of Psi Corp, but I can tell you that The League of Non-Aligned Worlds will be out at GenCon. That should please you, I hope. :)

So far that appears to be the going rate, but I imagine it will slow down here in a bit, unless they start doing B5's very own brand of Quintessential books or some such. There is a lot still in the works, but you should probably check out the B5 section and look up the future releases.
