To answer your questions...
1) The content of the new book is approximately 95% new. As I mentioned, the format for this book is closer to a huge episode guide with many paragraphs per episode with the cast/crew reflections. I didn't see a need to rehash the first book, but some information needed to be repeated.
2. We don't have a target price yet, but it will be under $50 for sure, probably less than that.
3. The book really is for the 30th anniversary of the original show - as such, it will only focus on the original series.
4. This is still up in the air. We need to see the cost of printing in color. It's even possible that we offer both B&W and color versions, with different price points.
5. The book will be roughly 6x9, making it the same size as Legacy. As far as thickness, we are still adding content so we don't know.
6. We have a couple ideas for the new book, all focusing around the 30th anniversary theme. Stay tuned
