Apple Thunderbolt Display Supplies Again Running Low at Third-Party Resellers
Several stores said they had limited stock, while a number more said they were backordered or otherwise completely out of stock. One retailer, Adorama, went further, saying the Thunderbolt Display was "no longer available".
MacTrast called their customer support line and were told that "the manufacturer is no longer allowing us to order new inventory for this item, and it has been removed from our system".
Shortages of products at third-party resellers can occasionally be an indicator of a future refresh or discontinuation, but for a low-volume product like the Apple Thunderbolt Display, we can get mixed messages.
For example, this past January, AppleInsider reported similar shortages of the Thunderbolt Display at third-party resellers, but 6 months later, there is no replacement for it.
Regardless, redesigned Thunderbolt displays are expected at some point, perhaps alongside the new Mac Pro which is expected later this year. Potential features for a revamp include Retina capabilities, support for Thunderbolt 2, USB 3.0, and the MagSafe 2 connector that was introduced last year. The display may also be redesigned with the thinner profile and new display assembly process that Apple introduced with the new iMac late last year.
