Certainly, that's what Apple notebook-oriented website O'Grady's PowerPage suggests, without citing specific sources. Apple has already dropped FireWire from the latest iPods - much to the annoyance of numerous Register readers with older, USB 1.1-equipped Macs - so it's clearly shifting its allegiance to USB 2.0, which while technologically inferior to FireWire is fast enough for almost all PC-peripheral connections.
According to O'Grady, the upcoming Intel-based iBooks will lack FireWire and x86 PowerBooks will have a single FireWire 800 port for digital video enthusiasts and professionals to make use of. And 1394, as it's also known, will continue in non-PC applications.
