According to 9to5 Mac, retail copies of iWork '09 are running low at Apple Retail Stores. As one Apple retail employee told 9to5, "There is no iWork on the shelves, no iWork in stock and none on the way." That alone is a pretty good sign Apple's office suite is about to be updated, but there's even more.

Apple just released iWork 9.0.4, the new version bringing a number of fixes to Apples's productivity suite but also deploying a new feature, this new feature is the ability to export Pages documents in the ePub format for compatibility with company's iBooks application for iOS.
