I'm merely a creative "hobbyist" rather than "professional". My own DAM system is PhotoMechanic + whatever RAW converter seems appropriate for an image. Aperture has been great as both a RAW converter and as a base for using Nik/Topaz/OnOne plugins. Personally, I've always found LR's interface pig-ugly and I don't care for it's workflow, though I do own the product. All this to say that I don't have a lot to lose with Aperture as an application going away. But to me, here's what we know:
* Aperture, iPhoto, iPhoto streams are going away
* New Photos app replaces these and will import Aperture, iPhoto libraries
* New Photos app does have have at least some fine grained control over images if the screen shots floating around are to be believed
* Apple is NOT pointing people to Adobe (TechCrunch has since retracted that statement)
* New Core Image API makes very sophisticated non-destructive extensions possible not only in the "filters" arena, but also noise reduction, lens correction, etc
* Brings iCloud storage and access to all images on all devices, including (as I understand it) RAW format, a direct competiton to what Adobe is trying to do with their CC Cloud approach and various apps, which to me seems muddled.
Bottom line for me is that i am interested to see where this goes and will not slit my wrist just yet.
