I have half a feeling that they are going to realize that dropping aperture was a mistake and introduce a replacement. Maybe a misguided hope, but (iirc) they advertised the retina MacBook Pro showing the benefits of the retina screen to edit photos.
I know professional users are not their main market (and haven't been for a long time) but there is surely a huge market of prosumers, many of whom have jumped ship to Adobe Lightroom. Seems an unnecessary self inflicted shot in the foot.
I know photos is a huge step up from iPhoto but surely they can't think it is enough?
If aperture isn't supported on osx 10.next I doubt I will be upgrading.
Glad they are still updating iMovie though, I haven't used it much but it is pretty good for my needs.
