An Infoworld.com story from last week notes that IBM is actively working on 90nm chips and actually plans on shipping these chips before long:

IBM is currently sampling 90 nanometer chips using SOI, and plans to ship those chips in the fourth quarter, said Scott Sykes, an IBM spokesman.

Current PowerPC 970s utilize a 130nm process. While no specific chips were referenced in the Infoworld article, a 90nm chip would bring higher clockspeeds and lower heat production as compared to the corresponding 130nm chip.

Meanwhile, an unverified report that appeared on Page 2 claims to have more details, but also claims a later ship date for the 90nm chips.
