But there is absolutely no standardization in 3D.
Just to be clear on this. The broadcast format, and HDMI data transmission for 3D standards have been finalized. It's just the display technology which is still being worked on. That's a good thing. Manufacturers are free to come up with innovative ways of presenting each eye's content to the appropriate eye.
For instance of a BD player had enough free CPU cycles (PS3 I'm looking at you), it could take the individual eye frames, tint them (red and green, or red and blue depending on which glasses are being used), combine them into one frame, and make it so people could watch new 3D BDs, on older sets. Albeit with the rather poor anaglyph technology.
