So Firewire is dead?

So apparently, FireWire is on life support--Jason O'Grady asks what our take is on the death of Firewire.

Well I'm not entirely surprised as it wouldn't be the first time Apple has fanfared the launch of a new technology only to drop it months later. I'd just like to check one thing, how are we supposed to boot the new Intel Powerbooks in target mode? Will this happen via usb2?
