FireWire isn't so obsolete yet after all. The 1394 Trade Association is boasting that two billion FireWire ports have already been shipped and implemented worldwide.
The Association, which is "dedicated to the advancement of the IEEE 1394 (FireWire) standard," naturally asserts that "estimates the total of 1394-equipped devices will increase" this year. Unfortunately, no specific numbers or estimates have been provided.
Additional future plans include a step-up to 1.6 Gb/s bandwidth, but hasn't USB 3.0 already beaten them to the punch?
