That's a bummer, I just bought Scipy and Numpy and was looking forward to reading it.
Another piece of advice for people: about 80% of Python for Data Analysis is the same as the online documentation for Pandas, the other 20% some examples and other notes. So if you're buying it you should buy it to support Wes McKinney, not to learn a ton of new stuff. Which wouldn't be the worst thing you could do, pandas is pretty awesome and I don't know what else you would use in Python to do statistical data analysis. (Of course there are separate tools for more specialized analyses and techniques like ML and NLP, but I mean "plain ol' stats".)
