It was reported today on the http://www.loopinsight.com/2014/06/27/apple-stops-development-of-aperture/
website that Aperture is being discontinued by Apple when Yosemite is released. I talked with a couple of the top contributors to the Aperture and iPhoto Apple forums and they heard that the info was legit but not officially confirmed by Apple. We'll have to wait and see.
If true the Aperture is going the way of iDVD, iWeb and the Dodo bird.
