I think given that many of apple's customers still work with audio and video, both of which often require firewire for cameras or interfaces. I don't think its the end of firewire just yet, until they make a high bandwidth replacement, or usb3 takes over as the standard.
didnt a newer FW standard get approved just a few months ago? I for one dont see FW dying unless usb 3 has the sustained transfer rates. Id actually prefer to see FW have more of a market share, but im always rootin for the lil guy lol
