More 3D titles are on their way in the horizon, but they are coming in the way of bundles and exclusive to hardware vendors. Sony is going to be releasing This Is It and Alice in Wonderland in 3D, each in a separate bundle. While Panasonic has acquired an exclusivity deal with Fox to release Avatar in 3D later this year for an undisclosed period of time. There is no word on when these titles will become available without a bundle or with a purchase of Blu-ray hardware. UPDATE: Bolt has joined to the list of 3D titles exclusive to Sony customers.
Also, Panasonic has announced their new 3D Essential Pack that will include 2 pairs of 3D shutter glasses, Coraline 3D Blu-ray and Ice Age: Dawn of the Dinosaurs 3D Blu-ray. Both 3D titles were previously available to new Panasonic Viera 3D TV customers only. The price of this bundle is $350, but you can find them here at a slightly lower price.
