The reason it's out of stock is because a new edition is about to be released. Its har to find in the US too, we were lucky to find a copy in Bishop. The shop in the valley was all out of stock.
Maybe you're not interested but Erik Sloan has been getting some flack on Mountain Project about his behaviour in the valley. Some people appear to be boycotting his guidebook for this reason. Anyway, have a search of their forums for more info.
