I'd also be very interested to see how the in-sensor Phase-AF works (and how fast), but mostly if it has any noticeable effect on IQ. Obviously some pixel real estate is being taken up to put in the sensors, i'd like to know how many and if it's noticeable (ie, I'm presuming they just do some kind of interpolation-algorithm to make up the missing detail, will that lose detail? Probably depends on how many pixels are sacrificed for phase-AF, if it's one isolated or if there's blocks of 10 or 20 missing in one place?).
Anyway, can't wait for the rest of it.

ps, typo: in the 'file size table' the first two lines are T3i, I presume one is meant to be the 650D (whatever that is over there, t4i?)
