Dive Into Python 3 will cover Python 3 and its differences from Python 2. Compared to the original Dive Into Python, it will be about 50% revised and 50% new material. I will publish drafts online as I go. The final version will be published on paper by Apress. The book will remain online under the CC-BY-SA-3.0 license.
