This year's topic will be "Divine and Human Freedom," with Dean Zimmerman as the keynote speaker. Also presenting will be Peter van Inwagen, Timothy O'Connor, Derk Pereboom, and Keith Yandell, among others. See the conference website here.
Zimmerman is a big-time metaphysician, and the biggest conference speaker Wheaton has had since van Inwagen in 2001. I don't know where I'll be living at the end of October, but I'm going to make every effort to be at the conference.
