You are correct! New Mac Pros are out.
Edit: There's only one new Mac Pro configuration with the quad core 3.0 GHz processor and it's expensive. As much as I'd love to have one of these Macs, just adding an ATi Radeon X1900 XT 512 MB graphics card, a second SuperDrive, Airport+Bluetooth Wireless, and a Wirless Keyboard/Mighty Mouse brings the cost of this Mac Pro up to $4,483.00! I'd also definitely want to put more RAM into a box like this but I definitely wouldn't buy the RAM from Apple at the prices they charge.
This is just about the smallest 'speed bump' I think I've ever seen (other than the infamous G4 'speed dump'). Only one new option across the line, no new graphics card options, no lowering prices on 'older' Mac Pros, etc.
