Little Brown will publisher what may be the very last book by David Foster Wallace. It's called "This Is Water: Some Thoughts, Delievered on a Significant Occasion, about Living a Compassionate Life;" unfortunately, the book will contain nothing original. It is the speech Wallace gave three years ago at Kenyon College. The parts I have heard from the speech are pretty incredible.
I'm still holding out hope that there is some little unpublished gem that will come up in a few years...
