If I could pitch a couple pennies in here... As a long time user of Photoshop (since 2.5) I felt thrown for a loop when I discovered that ImageReady was no more. Adobe claimed that CS3 offered tighter integration between PS and Dreamweaver, but that still didn't tell me how I was supposed to create and export button states in Photoshop like in the past. And I'm not alone; the Adobe forums were exploding with unhappy web artists who felt they were left to figure out for themselves what to do now.
So a section on "What to do now that ImageReady is history" would definitely fill a void that's been left by the recent upgrade. I'd also like to see some of the features in Photoshop Extended covered, such as how PS can now be used with video.
