Honestly, I don't think Apple is much concerned about "the Pros" not being satisfied as much as they are frightened by the prospect of pros dumping the Apple ecosystem entirely.
There must be some pretty damning internal numbers for Tim Cook to explicitly mention addressing the needs of pros in February's earnings call, and then for Phil Schiller, Craig Federighi, and John Ternus to meet with selected journalists to openly discuss their plans. I'm guessing they're trying to stop the bleeding and give themselves time to come up with a decent game plan.
I've seen a spate of articles lately from a variety of creatives (photographers, designers, video editors, etc.) blogging about dumping Apple in favor of Windows. Last week I put together a Windows 10 system for my sister and I gotta be honest here... I was fairly impressed with Windows 10. Give it some decent hardware (in my sisters case, about $600 worth of hardware), and you're golden. For the average [non-hack] person, that's basically impossible to do in Apple-land.
And for most people, it's about the apps anyway...
Photogs have Lightroom or Capture One (both of which run on Windows too), after Apple so ceremoniously dumped Aperture, and videogs have flocked to Premier (which runs on Windows too) when Apple released FCPX iMovie edition. Audio studios have a TON of options, most of which run on Windows too. IOW, there's not much to keep a pro, or budding pro, from jumping ship to Windows. And Windows is looking fairly good now with the Surface Studio hitting the streets.
