Well, O'Reilly recently reported that sales of of computing books in general were off something like 28% for 2008. So starting a new occupation (software archhitect) or pandering to those who'd aspire to the "title" may be a marketing strategy.

According to Amazon (http://www.amazon.com/isbn/dp/059652269X) the book was to be released Feb 13. I put it in my Amz shopping cart so I can let the reviews thereon tell me whether it's at least worth skimming it at Barnes & Noble (all that's available to me locally).
