Side note re the photo edit view, are there any particular features you think this would make sense for? In my experience, Photomator is pretty close to Photos in functionality. And broadly speaking, Pixelmator features don't make sense in Photos (for the same reason Lightroom and Photoshop are separate apps, they're designed from the bottom up around different approaches to photo editing). Based on those two facts, the only way I can make sense of this acquisition is that they want the Pixelmator app specifically, because that's the only part that would be really hard for them to reproduce in house, and I can't think of many reasons why they'd want that besides creating a new pro suite like this.
