[vtkusers] new book on VTK?

[Luca Pallozzi Lavorante]

Hi everybody,
I am planning to buy the last book on VTK (2003 edition) but I have read 
on the list that important changes are occurring in the system´s 
architecture for the 5.0 version.
So I would like to know whether a newer version of the book will be 
released in the next months.

   Many Thanks

        Luca
