AppleInsider reports that Apple is advising its direct and indirect sales channels of iMac shortages, specifically the 21.5-inch, 3.06 GHz model, implying that there will be a refresh in the coming weeks.

Also of interest, according to those same people, were indications that new iMacs would be the first Macs to employ Intel’s Core i3 processor at the low-end, which would have the new family of desktops utilize all three flavors of Intel’s mobile Core line of processors.

Also rumored is that Apple is in advanced discussions to adopt microprocessors from AMD, while Apple a 12-core Mac Pro and 27” Apple Cinema Display remain unseen.
