Firewire 2... here?
James provided this tidbit:
http://standards.ieee.org/board/rev/302recomm.html which seems to indicate approval for the new 1394b standard... posted March 20th 2002.
Interestingly enough, James also points us to this release which discusses the 'b' version:
He cited the arrival of the new b version of the standard, which provides a minimum of 800 Megabit/second bandwidth and extended connectivity for FireWire and i.LINK products.
... but the interesting part is that Apple's iPod is listed among the 1394/Firewire-2 devices - which could be read as "1394 as well as Firewire-2" devices... except there is a 1394/Firewire/iLink list immediately above it.
