ZDNet has an article discussing USB 2.0 vs Firewire, and quotes James Snider, executive directory of 1394 Trade Association: "By the end of the year, you will see it on at least one computer with 1394b and on consumer electronics products from a major manufacturer in Japan".
They go on to state that Firewire 2 will be shown at MacWorld New York according to their sources. This despite earlier doubts that the final silicon will be available.
Approval of the Firewire 2 standard came in March 2002. As well, a prototype motherboard that was placed for auction on eBay appeared to have a Firewire 2 connector.
