Apple retires the Thunderbolt Display without announcing a replacement
Apple has yet to announce an updated version of 2011's Thunderbolt Display, but pretty soon it won't be selling the old one either. The company will sell through any existing stock in the online and brick-and-mortar Apple Stores, but it doesn't plan to continue manufacturing the current model.
According to a statement given to TechCrunch, Apple is pointing its users toward third-party monitors. There are plenty of these and they come in all different sizes and screen resolutions and panel qualities and prices, though none offer actual Thunderbolt activity; regular USB hubs are far more common.
