What's Bill Simmons Working On?

At the end of another of his mammoth chats yesterday, prodigal Sports Guy Bill Simmons made an odd announcement.

One last thing: I started working on a book last week and ESPN has been gracious enough to let me cut back on the columns in July and August so I can work on it. Still doing the podcasts every week, still writing the mag column every 2 weeks, leaving the door open for 2-3 more columns for the website, but other than that, I have to start cranking out this book or I'll never write end up writing it.

We hadn't heard anything about any book, and we're curious what the topic is. Another Red Sox book is out — and since he's taking time off, we're assuming he's writing new material and not just adding footnotes — and we doubt he'd have the intestinal fortitude to write about gambling or Vegas or something. We are crossing our fingers it's about the NBA ... but, frankly, who knows? Suggestions?
