I just got the books, but I haven't got the CD's or the Teacher's guides yet.
My coteacher translated the little note on the page with all the chapter titles. It says the chapters are the same from the old book, but chapters 3, 6, 9, and 12 are new. They are review chapters for the preceding two chapters. Lastly, chapters 13-16 are all brand new.
