Appleinsider reports that Apple has received new 90nm PowerPC shipments and seeded several test PowerMac units to partners.
The test models are reported to range from 2.2GHz to 2.6GHz.
Meanwhile, Appleinsider notes that Apple Display upgrades could be delayed by oversupply of current units.
Rumors of PowerMac revisions have come and gone over the past few months. Earlier reports have indicated that Apple has already outsourced work for promotional materials for the new machines... but due to the unsteady supply of 90nm chips has been unable to commit to a ship date.
