DOCBOOK: Latest version of DocBook Guides

Hello,

Does anyone know when version 2.0.2 of "DocBook: The Definitive Guide" for 
(x)DocBook version 4.1 will be available in a non-web format?

The older version 1.0.3 (for DocBook version 3.1) is available as an SGML 
source document on
http://www.oasis-open.org/docbook/documentation/reference/

Thanks,
Pamela
