Due to the photographic nature of the show, there has been speculation that Apple would be releasing an update to Aperture. One user points out that Apple's Aperture feedback page asks users what version of Aperture they are using. Included in the pop-up list is Aperture 1.2, which has not yet been released.
However, the last released version of Aperture is version 1.1.2, which is not presently listed on the feedback page. As a result, the 1.2 version number may simply be a typographical error on Apple's Aperture feedback site.
