Where to find more info on Visual Studio 2010 package development?

I'm trying to find in depth guide on vs package development.

I've tried with a few books (Visual Studio 2010 Package Development by Istvan Novak, http://www.amazon.com/Professional-Visual-Studio-开发者_高级运维Extensibility-Nayyeri/dp/0470230843/ref=sr_1_1?ie=UTF8&qid=1314871900&sr=8-1).

Im interested in VS architecture, services, and internal components useful for Package development.

Does anyone know about more resources for this, books, sites, documents?

DiveDeeper's blog has a very good set of articles too.

I guess a book was to be published on VS Package development (by Aug 2010), I cannot find it in Amazon however.

DiveDeeper has listed all his articles on codeplex now.

I've found the mztools site to be very useful, an accumulation of many articles and examples.
