As you can see in the screenshot above, it references a 27-inch iMac for mid-2014. Considering that the last iMac refresh took place last month and it was for the 21.5-inch iMacs, we guess it is also about time that Apple refreshed their 27-inch iMac as well. However Apple has yet to make any announcement and last we checked, the Apple Online Store’s listing has not changed.
Now there have been rumors suggesting that Apple could be getting ready to introduce a 27-inch iMach with Retina display, at least according to files spotted in OS X 10.10 Yosemite, but as whether or not that model will actually launch this year remains to be seen. Some speculate that Apple could be going the entry-level route and introduce a more affordable 27-inch iMac.
However given that the 27-inch iMac has typically been Apple’s high-end offering, it doesn’t really make sense. In any case make what you will of the listing in the support document, but hopefully Apple will announce something soon.
