A book listing on Amazon.ca suggests that Apple is at work on a new version of Aperture, AppleInsider remarks. The listing is titled "Apple Aperture X - under NDA: A Workflow Guide for Digital Photographers," and mentions a March 1st release date. It appears to be a placeholder though, as the description talks about Aperture 3, and "under NDA" is a reference to a non-disclosure agreement that Amazon and/or the publisher appear to have broken.
