jema - I agree with ya.
As for when it becomes standard, well put it this way. If it's built into the southbridge and your competitors are including it, who's not going to include 1394? Like nortexoid said, it's already in a few and will be in all relatively soon.
I finally bit the bullet and ordered two firewire cards this morning with the intention of using them for networking my two computers to start with (they're side by side, distance not a problem, why blow more money on new ethernet?) and then they'll be ready when I pick up an external drive. Figuring my future motherboards will have both so it better become standard 🙂
