haha - its not a lack of enthusiasm, it is just that they do not perform (as we understand performance currently) - you can't open as much instances on a G5 as you can on a macPro ... is it the little vs. big endian thing or the processor pipeline, don't ask me why in detail ...
the 8-cores ... if you like to hear my opinion ... they are only a minor step forward in relation to the last generation macPros, actually not even compared to the 4-cores. i'm not even sure everything is scaling as expected across the 8 proc. intel themselves releases some *code optimization tool* lately to allow full access to the capabilties of these processors ...
regarding several reports about the new firewire chip and strange USB behaviour it would maybe a good idea to let their first release pass by until everything is clear ...
as i read the news the Q9000 (quadcore penryn) series is a little bit delayed but should be delivered soon.
my 2c only, christian
The "Harpertown" in the new 8-core Mac Pro _is_ a quad core Penryn - as I understand it, the Q9000 is a "Core" (not "Xeon") line of the Penryn family, which means it will be targeted for future iMacs, not Mac Pros. El Reg clears things up a little:

See: clear as mud! 😉
But, I have to say a "minor step forward" they most certainly are not. Lower power (and virtually silent), faster, cheaper, pci-e 2.0, and so on... I'm also really curious about rumors suggesting that OS X 10.5.2 will somehow make use of SSE4 - if it does, then we should see significant performance gains in certain areas. Time will tell, I guess. I bought the day after this revision was released - in spite of long history with Apple, which has made me fully aware of the potential dangers of buying "rev a" anything. However, my feeling was that most of the development in this revision was coming from Intel, not Apple, so the logic board _design_ shouldn't have changed too much (just the various chips running the show). Anyway, no USB or Firewire problems to report, at this early date. My audio interface is Firewire (Apogee), and it's been flawless.
As revisions go, obviously the next gen will be "better", but it will probably continue to build on the current Penryn line. If you have the patience of a saint, and basically don't need to get anything done this year, then wait for Nehalem - that promises to be a real beast. For myself, I had already waited several months for Penryn, and I'm glad I finally "jumped in".
