Then again, where's our eye tracking?
Personally I don't see them releasing the eye control option again any time soon and I'll tell you why...
1. The simplest reason is liability. People already are griping about the 45 pt af and more options such as eye controll can be a bigger backlash. The amount of calibration, testing... People moan that they need to do the microadjust let alone calibration... If it doesn't work perfect out of the box be prepared to read floods of forums... This af is horrible. Part b to this answer if professional photogs don't JUST look at the subject matter in the view finder, were looking at the scene, the background blur, the composition, looking for anything that would detract... If a photog looks off subject consciously or unconsciously for a split second before clicking the shutter, you just lost your focus assuming you didn't lock ur focus. Even if it was user error, people will still slam canon and NO one will accept responsibility. In this saturation of pro photogs not seen by any other time history of Photography, it's a huge liability.
Second, with digital, with high mp, focus needs to be perfect. Any flaw will be magnified since people are pixel peeping more than ever, so unless it is perfect, forget it. Too much of a risk. At least with af points you can select 1 point and keep it on subject to eliminate equipment failure from the poss why your shot is OOF.
