Subject recognition, yes. Nikon has been doing this for ages, even with less resolution. Their 3D AF tracking is based on it (and works very well, btw.)
Face recognition: maybe.
Eye recognition: certainly not. The resolution to do that reliably (!) is simply not there. And there's one more glitch: even if the metering sensor properly detects an eye, there still needs to be an AF sensor at that spot to actually focus on it. With typical AF systems, chances are, there is none. And if if there happens to be one at exactly the desired spot, chances are it's too big to cover the eye only. Or, in other words, to reliably focus on the eye, not the eye lid or the lashes.
