We can only hope the Apple continues to want to serve the developer and professional community ... not just the prosumers and college kids building one iPad app, but serious pros.
If that's the case, then the only hope is that the MacPro and iMacs will be completely rethought with that service in mind - case design, processor choices, modularity, etc. The extant MacPro design isn't really much different than an old G3 tower, except it's metal and looks like a cheese grater.

PS: I just bought the 6 processor MacPro - couldn't keep running the old G5 quad any more. Can't run any new apps, etc. Did save money compared to last week, though.
I don't know about the iMac (because really, it is just a cinema display with a computer in it...not much to rethink) but the Mac Pro, yes, they are probably completely rethinking it. Whether that is good or not is another question (a lot of people hated Final Cut Pro X). I wouldn't be surprised if we saw something more modular and takes advantage of Thunderbolt beyond "here is a port that can replace firewire, display port, and ethernet". What sucks is that if they really are doing this they won't tell us until it is nearly ready to ship if not shipping. After the insanely bad "update" that happened today they could start hemorrhaging customers. They need more than to have one of their approved outlets repeat an empty statement. They, frankly, need to do a Back to the Mac style event but for the desktop hardware (it killed the "Apple doesn't care about Macs" meme and now we're left with "Apple doesn't care about Pros/desktop" meme).
