I personally don't think they are mutually exclusive. Although having a 3D image means that each image is at half the resolution of the entire screen (or half the framerate), it doesn't remove that systems ability to display full non-3D images. I get the feeling that the cheapest, best stereoscopic technology will be sifted out over time and that adding it onto an otherwise non-3D TV will be trivial enough that HD and 3D will merge with each other rather than beoming competitors. ~Change is Silver Author of "How to Make a Holodeck" (5Deck.com) and Creator of Unili arT (UniliarT.com)
See more about MVC (http://en.wikipedia.org/wiki/Multiview_Video_Coding) and the link with H.264/MPEG-4 AVC (http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC) and search the text saying "all Blu-ray Disc players must be able to decode H.264". In other words, the default standard to 3D movies is a update in the standard to Full HD in Blu-Ray and HD TV broadcasting.
