None of those are Pro requirements.
LOL seriously? you think pro users care about USB 3.0?! Get real.
If you want to know what a PRO user needs, ask a TV production company.
I'm a pro. I use usb 3.0. Out of all the "pro" users and by this I'm assuming you mean the ones who making their living working on a Mac Pro, the percentage of those that work for TV production companies are the vast minority.
I've worked in studios and saw companies who overspend ridiculous amounts of money on hardware that most of the time is unnecessary. I use usb 3.0 drives all the time to archive projects. $150 for 3TB, backed up on duplicate drives.
It's not just home users and production companies, there is a huge segment that fall in the middle.
