The report claims that Apple Stores around the world like in North America, Europe, and Australia are apparently low on stock on Thunderbolt Displays, or just outright do not have them in stock anymore. This has led to speculation that maybe Apple has not bothered issuing new stock as they are planning to introduce new hardware at the event.
It is also entirely possible that Apple might decide to kill off the display, but we reckon a refresh seems more likely of the two. It will also be interesting as in the past few years, WWDC has become less about hardware and more about software, whereas previously Apple would announce hardware like the iPhone at the event, so it remains to be seen if Apple could announce new displays at the event or just refresh them quietly in the store.
It has been speculated that the new Thunderbolt Displays could be of the 5K variety to match the 27-inch iMac. In any case take it with a grain of salt, but WWDC is around the corner so check back with us in the coming weeks for the details.
