As always, it is worth pointing out that "3D" would be a terrible name for any camera that did not do, you know, *actual* 3D. It would set up that exact expectation in consumers' minds. -snip-
Edit: lonelywhitelights said it first.
I think you are underestimating folks just a bit when you say this. The group of pro and advanced amateur photographers who are able and willing to drop ~$4000 on a camera body are probably going to be bright enough to figure this out, don't you think? Sheesh.
And I think it will mean that whoever thinks it is 3D, is only looking at one model - else they will definately buy the 5D, I mean, a fourth and fifth dimension must be amazing!
The EOS 3 camera was an amazing film camera and got me hooked on Canon - it will be great to see the same level of camera in the digital range. Just wonder if they will bring back an advanced eye sensor to assist with the focus point selection.
