The comments so far have been a little tame compared to what i've read elsewhere about bringing it back, some people hated it with a vengeance. But maybe they just didn't realise that it could be switched off (similar to Video, maybe? Lots of people don't use it, so don't want their R&D Dollar spent on it).
I've used it a tiny bit on my sister's EOS 5, didn't 'train' it enough to get any proper use out of it.
I'd be happy if they put it back in, most of the R&D money was spent 10-15 years ago anyway, won't add that much cost to the camera. But I'm also perfectly capable with my 7D's joystick on the back to change AF point. Depends what you can handle more, RSI in your thumb, or RSEye... (groan).
Still, no rumours, except that paper I read a week before the 1DX dropped here
Even as innovations like 45-point Area AF and cross-type AF points have led to more compositional freedom and broadened the possibilities of photography, we are still devoted to developing in the near future AF technology that will focus where you want it just by thought alone without any physical operations. This “dream AF” will astound you all.
I wondered then if that was referring to Eye-control, I presumed after the 1DX was announced that it was for that, but now i'm not sure, they could still be referring to Eye control (or ESP?)
