I found this article that lists devices that should/will get the 4.4 update. It even lists devices that are testing for it as well.

* A report from SamMobile has now suggested that the Galaxy S4 mini, Galaxy S3 mini, Galaxy S Advance, Galaxy Ace 3, Galaxy Core, Galaxy Fame, Galaxy Ace 2, and the Galaxy Fresh are the devices which they are testing the new OS version on, so it would be a possibility for these devices to run the Android 4.4 KitKat, not very soon though.
