Contrary to some reports, Apple's new iMac is still on track for release this year, says 9to5Mac.
Our sources say that Apple is already shipping new 21.5-inch iMacs to its distribution hubs across the United States and several other countries across the world. These sources also expect the 21.5-inch computers to be available to order from Apple’s online store by the end of this month. It is also likely that the new models will reach Apple’s physical retail stores by the end of November.
The site's sources say the 27-inch version appears to be launching in December; however, there is a high chance you'll be able to order them online at the same time as the 21.5-inch models.
