RTC/Jazz article series on developerWorks - when continued?

In June 2008, part 1 of an article series about RTC and Jazz was published on developerWorks:

Part 1. Installation and Setup
http://www.ibm.com/developerworks/rational/library/08/0701_srivastava/index.html?S_TACT=105AGX15&S_CMP=LP

Other parts were announced:
Part 2. Defining the data model for the project
Part 3. Defining services for data access
Part 4. Developing a Web user interface to view data
Part 5. Creating build configurations and reports for analysis

Any ideas when parts 2 to 5 will be published?
