Amazon has listed both the 3D and 2D versions of Titanic for Blu-ray pre-order.
The online retailer is listing the 3D edition as a Blu-ray 3D/Blu-ray/UltraViolet Digital Copy combo pack and the 2D edition as a Blu-ray/DVD/UltraViolet Digital Copy combo pack.
However, at this moment, Paramount Home Media Distribution and Twentieth Century Fox have not released any of the technical or supplementary specifications for each of the respective packages.
Note: While the distributors have also not set a firm street date, Amazon is listing its release date as September 14th. Furthermore, Amazon is offering a $3 credit to those who pre-order either the 2D or 3D version.
The pre-order cost for the Titanic 3D is currently $27.99 (or 49% off its SRP of $54.99), while the 2D combo pack costs $21.99 (or 51% off its SRP of $44.99).
