Yeah, it's pretty much in a vegetative state and waiting for someone to pull the plug and put it out of its misery.
Proprietary solutions very rarely last the course and die quick deaths because they only have access to the more expensive segment of the market. Technically, Firewire 400 is greater than USB 2, but with USB 3 ubiquitous, available and open, Firewire no longer has a reason to exist.
I have one Firewire 400 port on my Asus P8P67-M Pro and I have a Firewire capable WD MyBook Studio. Ironically, the performance of the MyBook is better in the USB 3 port (despite only being USB 2 device) than on FireWire.
I heard JJ from Asus saying in a motherboards.org YouTube video that one of the criteria which governs what they will put on a motherboard is: "Are more than 25% of our users likely to use it?". Clearly with FireWire, the answer has become a no, so it is being phased out. The opposite is occuring with Thunderbolt which is now being brought in at the high end and will filter down to the mainstream later.
