A Xeon class CPU is quite a bit different than the mobile/desktop class CPU Apple puts in their other systems. I think Macro is being a bit dramatic in that a stagnant Mac Pro means the end of an era and I call bullocks! Intel's Xeon chips do not advance at the same pace and have themselves stood still. Look at what Dell and HP are selling, they're basically the same CPUs (albeit you can buy one generation newer). What the Xeon workstation/server architecture provides is a fat I/O pipe that's still extremely important to music and video professionals who rely on near zero latency. Even photoshop cringes when working in print media scale designs that take up a couple gigabytes in a document. Besides, Apple tends to move slowly when a product isn't front and center, usually milking a design for all it's worth. Tim Cook said they're working on a pro device that will be out this year and I believe him.
