THE SPECIFICATION for 3D Blu-ray has been finalised by the Blu-ray Disc Association (BDA) so it shouldn't be long until we can all fork out another wodge of cash for new kit if we want to buy into 3D.
Jumping on the 3D bandwagon, the BDA has decided we need our headaches to be created in full 1080p high definition and is attempting to thwart the traditional format war by coming out with a standardised spec as quickly as possible.
The specification uses the Multiview Video Coding (MVC) codec, an extension to the ITU-T H.264 Advanced Video Coding (AVC) codec currently supported by all Blu-ray Disc players. MPEG4-MVC compresses both left and right eye views with a typical 50 per cent overhead compared to equivalent 2D content. It also provides details on other features such as 3D menu navigation and subtitles.

The BDA has said, "The Blu-ray 3D specification calls for encoding 3D video using the "Stereo High" profile defined by Multiview Video Coding (MVC), an extension to the ITU-T H.264 Advanced Video Coding (AVC) codec currently supported by all Blu-ray Disc players. MPEG4-MVC compresses both left and right eye views with a typical 50% overhead compared to equivalent 2D content, and can provide full 1080p resolution backward compatibility with current 2D Blu-ray Disc players."[155] This means the MVC (3D) stream is backward compatible with H.264/AVC (2D) stream, allowing older 2D devices and software to decode stereoscopic video streams, ignoring additional information for the second view.

Where are you reading that there is a choice of codec, bitrate, refresh rate, or resolution? My read of the above is there is one codec, one bitrate, and one resolution. Did something change?
