I think I'd be wary of such a feature. I take pictures all the time of my kids, friends, dog, etc. Getting everyone to look at the camera at the same time or with eyes open is a real pain. I'm not sure I want an algorithm choosing to keep the best photo at the expense of what I mentioned above. EVEN WITH the ability to accept or reject, if I'm shooting a bunch of photos all at once (say at my kids sporting events) I may not have time to review and choose the one I want to keep. I'm not sure there's a great way to get around these issues other than perhaps to have an 'on-off' toggle or to have the ability to always to photos in this mode and then be able to decide at a later time which one to keep.
I'm fairly certain they will have an On -- Off function similar to the way you can toggle HDR On or Off. If that is the case, you're point is moot.
