Of course there are no 'hard facts' - nothing has happened yet and both Adobe and Apple are renown for not being especially forthcoming.
Yes, Hogan (along with half the planet) doesn't like Adobe. He's been pretty negative about the whole Creative Clown, er Cloud, thing. But his underlying premise is interesting - that this is the first step in Apple rationalizing a photography workflow. It's not 'the' photography workflow and may not fit many professional / prosumer goals - but that doesn't appear to be Apples audience. Perhaps. Hard to say since, again, Apple isn't terribly forthcoming.
But you have two big hitters in this space: Apple and Adobe. It will be interesting to see how this falls out. For my purposes, I've never liked Aperture / iPhoto. The workflow just doesn't fit with how I do things and isn't terribly flexible. I've actually enjoyed Creative Clown as I get to use After Effects and Illustrator for a perfectly reasonable price but YMMV, but I can't stand Lightroom. No matter, Adobe has recently started behaving better. You can now keep old versions running for as long as you like. You can download CS6 - forever. Yes, subscriptions are annoying but so is pretty much everything else these days.
