Zune Game Development Using XNA 3.0 by Dan Waters will be released on March 23rd.

Here's the product description:

XNA 3.0 brings you the ability to create games that will run not just on the PC and Xbox 360, but also on the Zune mobile device. While creating games for Zune is, in many ways, similar to working on the other platforms, it also presents its own unique set of challenges and opportunities. Smaller screens, limited storage, and less processing power all affect the way you need to think about designing and implementing your games.

Zune Game Development Using XNA 3.0 is a comprehensive book that will guide you through the many aspects of XNA game development and their specific implementations on the Zune platform. The book addresses Zune game development concepts in detail and shows you how to apply them in practical, step–by–step examples, building complete, working XNA 3.0 examples along the way that you can download and play.

I primarily do business development, but the idea of making games for my Zune is just too good to pass up. I think I'll pick this book up next week.
