Many expected Apple to release an updated iMac during the WWDC 2012 keynote, but the company decided to focus squarely on its Mac notebooks instead as it pertained to hardware. It's now been 427 days since the iMac last saw a refresh, and DigiTimes is reporting that we'll see the new models ship in October. Of course, no one but Apple and its manufacturing partners know all the details, but we've got our fingers crossed that we'll see a Retina display model on store shelves by the time Halloween rolls around. At the very least, expect Ivy Bridge architecture with Mountain Lion as the shipping OS.
