Listen you clearly haven't done your research. I am not about to regurgitate the data that has already been said dozens of times over in this very forum no less. An 8-core Mac Pro for $2500 is entirely possible and expected with the introduction of the new Harpertown chips from Intel. Again, do your reasearch.
In no way am I attempting to suggest we attack technological update cycles. Yes Yes, I know the Mac Pro will be outdated in a few months of its release blah blah blah. I am sure you don't know why, do you? Of course not, but it would be Nehalem that renders the Mac Pro obselete.
The Buyers Guide is hardly a definitive guide to Apple products. Furthermore, they are considering the ADDITION of the OPTION (Dual Quad Clovertowns) as an update, and they clearly state that the rest of the line was UNTOUCHED. That is hardly an update. Yes, the addition of a $1500 option is not an update. If you take a look here:
http://support.apple.com/specs/, you see one Mac Pro in that list. It is from August 2006. So even Apple doesn't take the addition of the 8-core option as an update to the line. If you want to see the true number of days, take a look at the XServe.
Shall I give your more evidence that the Mac Pro hasn't been updated, refreshed, whatever you want to call it in over a year?
