Query: an outstanding book but somewhat outdated

This book is the most comprehensive book of cell biology I have ever read. I think it is still better than Lodish's Molecular Cell Biology, even the 4th edition of the latter is updated. It helped me greatly in my preparation for GRE Biochemistry, Cell and Molecular Biology Test (I received a score of 750, 98%). However, 7 years have passed since this edition and many progresses in cell biology have been made in these years and a new edition is needed. It is said on Medscape Bookstore that the 4th edition of Molecular Biology of the Cell is due to be published in 2002-04 and now I am waiting for it.
