Earlier, we posted new iPad SKUs showing Apple is likely launching 24 new models of the device. It is still to be determined whether the four variants in the SKUs include updated iPad 3 models with Lightning connectors or four iPad mini variants. Today, we also get a hint at what looks like updated 21-inch and 27-inch iMac models from the same SKUs.

Listed as “D7″ and “D8″ in the SKUs above, we see two refreshed models. They are presumably for the 21-inch and 27-inch variants that Apple currently sells. We have recently heard reports that Apple is planning to introduce new iMacs alongside what reports claimed were images of the refreshed iMacs’ internals.

There have also been rumors that Apple will begin selling the refreshed iMacs on Oct. 24—one day after the rumored date of the iPad mini launch event. We are not sure Apple will begin shipping any of the new models on Oct. 24, but we have heard at least some varieties will not ship at launch. However, the SKUs above are pretty good evidence that refreshed models are on the way. We will have more on that in the near future.
