Tachyon Publications has posted the Table of Contents for their Rewired: The Post-Cyberpunk Anthology (edited by James Patrick Kelly and John Kessel), and it's a killer line-up:

• Introduction: Hacking Cyberpunk by James Patrick Kelly and John Kessel
• Introduction: Kessel-Sterling Correspondence by John Kessel
• Bruce Sterling "Bicycle Repairman"
• Gwyneth Jones "Red Sonja and Lessingham in Dreamland"
• Jonathan Lethem "How We Got Into Town and Out Again"
• Greg Egan "Yeyuka"
• Pat Cadigan "The Final Remake of The Return of Little Latin Larry"
• William Gibson "Thirteen Views of a Cardboard City"
• David Marusek "The Wedding Album"
• Walter Jon Williams "Daddy’s World"
• Michael Swanwick "The Dog Said Bow-Wow"
• Charles Stross "Lobsters"
• Paul Di Filippo "What’s Up, Tiger Lily"
• Christopher Rowe “The Voluntary State”
• Elizabeth Bear “Two Dreams on Trains”
• Paolo Bacigalupi "The Calorie Man"
• Mary Rosenblum "Search Engine"
• Cory Doctorow "When SysAdmins Ruled the Earth"

That second "introduction" is actually a series of letters between Bruce Sterling and John Kessel starting in 1985, which sounds like it's about the heart of the cyberpunk-humanist split. I hadn't even suspected such a thing existed, and I can't wait to read it myself.
