Put simply we’re doubling down on our investments in Lightroom and the new Creative Cloud Photography plan and you can expect to see a rich roadmap of rapid innovation for desktop, web and device workflows in the coming weeks, months and years. We also continue to invest actively on the iOS and OSX platforms, and are committed to helping interested iPhoto and Aperture customers migrate to our rich solution across desktop, device and web workflows.
Adobe's Creative Cloud Photography plan (which includes Photoshop CC and Lightroom) is a $9.99/month subscription, but the app is also available as a standalone purchase.
I personally never needed Aperture or Lightroom, but I know a lot of people who have been using Adobe's app for several years now. According to Apple, functionalities from Aperture will be integrated with the new Photos app for OS X – the screenshot chosen for the announcement today is interesting.
