This appears to add further evidence that Apple may be considering changing the name of the PowerMac to "Mac Pro" in the near future. Apple rebranded the PowerBook in January to the "MacBook Pro" and subsequently dropped the iBook name in favor of "MacBook".
Steve Jobs had indicated that they were moving away from the "Power" name when the MacBook Pro was first announced:
It's a new name [MacBook Pro] because we're kinda done with 'Power' and because we want 'Mac' in the name of our products."
