With MacWorld Expo still underway, questions about future hardware upgrades are already making the rounds.

iMac and eMac upgrades are on the way... as previously rumored... though no confirmation on upcoming processor speeds... though unconfirmed rumors seem to be guessing at 1GHz speeds.

PowerMacs were last updated on August 13th, 2002. That upgrade brought us Dual 1.25GHz processors. Another upgrade is expected, and should top out at Dual 1.43 GHz.

The new Powerbooks already have Mac OS X 10.2.4 loaded (more photos), and should be coming down the pipe for the rest of us.
