The 27-inch iMac is playing hard to get for some customers, which could mean that an updated version of the desktop Mac is on its way.
MacRumors reports that at several Apple stores, some models of iMacs are no longer available for in-store reservation and pick-up, suggesting that Apple has let the supply run out. It follows a rumor last week that Apple is gearing up to introduce a fresh update to the all-in-one desktop. Apple hasn't released a new iMac since October 2009.
Apple could be unveiling a new wide-screen (16:9) Cinema Display soon as well, according to John Gruber at Daring Fireball.
There's also speculation that a new set of desktop apps could be arriving soon. AppleInsider reports iLife '11 is coming on Saturday, August 7. The unusually specific date for the rumor comes courtesy of a French Apple blog that has a source pinpointing that day.
