Appleinsider claims that Apple will be introducing new iPods and Pro Macs in October.
The 5th generation iPods will revise the hard drive based iPods and are rumored to provide improvements in size/form factor. The new iPods are believed to utilize a higher density 1.8" Hard Drive from Toshiba which are available in 40 and 80GB sizes.
Also expected soon are upgrades to the PowerMacs and PowerBooks, but little definitive information is available on these upgrades. Appleinsider previously expected hardware announcements at Apple Expo Paris. Other sites also predicted PowerBook updates for Paris... but no hardware announcements came at the expo.
Dual-core PowerMac updates have been rumored since the announcement of Dual Core PowerPC chips from IBM.
