I just stopped by the Apple Online store and saw that their ad banner at the top of the store said new lower prices on the 12" and 15" powerbooks. I saved the image to post here. I also noticed that when I clicked the ad...the actual prices hadn't been adjusted but I think they may have just changed them shortly before I got there...it's 3:22am here. Anyway, maybe they're clearing inventory for new models?? Why no discount on the 17"? Who know.
[EDIT] As of 3:46am the correct (and lower) prices are now post to the Apple Store.
