MacBook Pro - Mac Towers Likely To Get USB 3.0 First?

MacBook Pro USB 3.0 PCI Express Card Bus
Given the easy upgrade potential to USB 3.0 via PCI-e slots in a Mac Pro desktop -- Or via a USB 3.0 ExpressCard in a MacBook Pro's Express card slot - I'd venture to say the early adopters and testers of the USB 3.0 specification on these Apple computer models will likely occur BEFORE Apple actually ships Macintosh systems with USB3 ports on the motherboard. But without USB3 SuperSpeed drivers in OSX Leopard from Apple...

Even then, here's predicting Apple will ship this new technology only PRO class Macs -- then once there's a true selection of cables, add-ons and USB SuperSpeed peripherals will this likely be rolled out to the MUCH larger market in consumer machines. We've seen this before when USB 2.0 arrived on high-end Macs first, again when the jump from 400 to FireWire 800 came to the Pro machines first.

In a way that's good: Apple can roll-out a new serial bus technology to a smaller customer base, let it go through some of the initial teething pains, slip-stream upgrade to improved Rev. B USB controller chipsets, make minor Firmware and OSX adjustments -- and then deliver a much more robust and stable USB3 solution to it's much larger MacBook, iMac and Mac mini customer later in the development cycle.
