Visually, it looks like the Firewire 2 port.
Spacially, it would make sence that it would be located next to the firewire 1 ports.
Timing wise, it makes sence to come out with firewire 2 soon because USB 2.0 is out.
As for number of ports: If they removed all firewire 1 ports and replaced it instead with one firewire 2 port, everyone would complain that they had to buy adapters out the wazoo to run their current peripherals. In addition, there maybe some new digital lifestyle device that is a bandwith hog that just might not like to daisy chain with other devices. For example, a high bandwith "box" may not like having a firewire external HD attached to it (as it might cause a lessening of 'signal')
That's merely my humble opinion.
