to those that laugh at blu ray already being more than enough i have two words: glassesless 3D.
In development is an extension of the MVC extension called MVD (Multiview Video Depth), also called 3DV. MVD adds extra data for additional "depth" layers and multiple views (probably more than a dozen) to create a multi-level stereoscopic image that you won't need glasses to view.
To decode, generate and view these multiple "views," however, requires a lot more signal processing power, resolution and new methods of display than available using current plasma and LCD 3D technology. First, you need ultra HD 4K, capable of displaying around 8 million pixels; current HDs display around 2 million pixels. At CES, Panasonic hung an astounding six-foot-wide 4K plasma, pictured, which also was used inside its 3D demo room.
