I don't see anything strange about the possibility of new Mac Pros, but I would if they were anything but a minor maintenance upgrade. I would like to underscore with all seriousness, that the disinterest Apple is showing the Mac doesn't mean the Mac is dead or dying anytime soon.. but in 5 years, continuing this same trend, then we'll be looking at a non-pro Mac line and in another 5 years, all laptop-line of Macs, running iOS (which will certainly be far more capable then, than it is now)
Point being, it's a slow downward spiral, and as such there is full reason for Apple to rewrite FCP. The rewrite was started more than two years ago anyway, and back then the future of the Mac was far brighter than it is today.
The Mac may be a nuisance and perhaps a distraction from Steve Jobs' vision, but Apple will muddle through with this distraction for a few more years before starting the wind-down in earnest (i.e. stop the maintenance upgrades and cutting down development of desktop machines entirely)
Hopefully this won't happen - I'm a big big fan of the Mac and hope it lives at least as long in it's OS X incarnation as it lived in the System 1-9 incarnation.
Okay, about the iOS paranoia. It's not a "downward spiral." There would be no iOS without Mac OS X. Thus, iOS will always be a subset of OS X, even if they wind up rebranding them under a single name. But even in that case, iOS will then be "upgraded" to OS X, not the other way around. I never thought I'd be one of those laptop guys, who actually spends more time on the laptop than on the desktop, but I sort of became one. My Macbook Pro was outperforming my 2008 Mac Pro for a lot of jobs, so it's just kind of happened. If and when some future iPad outperforms my Macbook Pro, then maybe I'll slip into using that, but the WORK is fundamentally the same.
Think of it this way, 10 years ago no Mac tower could access as much RAM, HD, etc. as the current entry-level iMac. So, doing the same job, a current iMac would kick an older G4 tower's ass in every department. Which is to say that the definition of a "pro" machine has only EVER been a question of how much WORK you could do on it. If I can do all that work on a future iPad, then so be it. I can't see how it's possible, but that may just be a lack of imagination on my part. Obviously, things like having a proper keyboard and reasonable screen real estate are important for my work, but you get the idea.
I also want to point out that people talking about FCP X being "prosumer" are absolutely full of crap. It's a joke. There is no "prosumer" (whatever that means) user who would ever make use of all the features FCP X has implemented. People are just getting pissy because it looks kinda like iMovie. It's a joke. People around here are so sentimental. In all honesty, there's nothing more ugly and ridiculous than the average PC. They SHOULD go the way of the dinosaur. People bitching about leaving PCs behind are like people bitching about history phasing out those all-in-one, furniture cabinet "high-fi" systems from the '70s. Those things were truly, deeply fugly. And other than losing some massive piece of entirely useless furniture, home audio never looked back.
