Based on product cycle timelines, Apple's iBook is the next model due to be updated. Apple last updated their iBook in April 2003, equiping the consumer laptop with 900MHz G3s at the high end.
AppleInsider's recent PowerBook report, which was proven to contain accurate information, also offered a few hints at upcoming iBooks. According to that report, Apple is "readying updates" to their consumer notebook and will bring the iBook up to par with the rest of their line with USB 2.0 and Airport Extreme support.
Assuming Apple continues to use the G3 processor, the most likely candidate is the IBM 750GX processor which is targetted for production in December 2003.
The PowerPC 750GX will be offered at speeds up to 1.1GHz with 1MB of L2 Cache. This represents an upgrade from 512k L2 Cache in the current iBook processor (750FX). While there have been numerous unverified reports of Altivec-enabled G3s, few reliable reports of this have emerged.
