Earlier in June, we talked a bit about the shortages of the Apple AirPort and Time Capsule devices and figured at the time that the shortages pointed to new models coming. We also heard that the new devices might have the ability to cache software updates for all sorts of Apple gear from your iPhone to your MacBook so you could update all your devices from your local network. The new devices and the caching feature have now been confirmed.
The confirmation comes from the source code of the new Airport Utility update. The geeks over at 9to5Mac were perusing the source code and noted references to new Time Capsule 802.11n 4th generation and AirPort Extreme 802.11n 5th generation devices. Further down in the update they also noted the code in the image with the white background.
That code confirms the update caching on the devices. The code also notes that the updates will be offered to anyone on the wireless network that the Time Capsule or Airport Extreme reside on. The only details we need now are the launch date and how much the devices will cost.
