Ciscopress IPS Exam Certification Guide

Hi,
I just got the Ciscopress IPS Exam Certification Guide (from 2006, by Earl Carter) cheap from an internet auction site, and I see that it is for the 642-532 exam.
I just took the SNRS-exam, so I have som insight into IOS IPS. I had an old Ciscopress book for the SNRS too, so I had to read up on how to configure 5.x signatures from other sources.
Will the Ciscopress book I got for IPS also cover old technolgy, or are IPS sensors not so affected by the version 4/version 5 signature changes?

On another note, I know a few people with the CCSP but not a lot of people use the Cisco IPS, I wonder if that means that it is not commonly used
