And: will the body size be getting smaller or not?
For both I hope not...
And the big question is can they nail good, fast, accurate AF that can track action without a mirror?

As long as the mount module is a standard part across the bodies, the cost of the system may stay reasonably low. Such mount modules may include an E, a full legacy A, a no-screwdrive A and then maybe some fully electronic 'post-A' type.
After yesterday’s post about Sony removing the SLT tech form the APS-C series quite some people got scared that this also means the end of the Alpha Mount lines. I keep stressing you that this isn’t true and that the A-mount line will keep being developed. Three years ago Sony switched from Optical viewfinder to Electronic Viewfinder with translucent mirror. And next year we will see another switch (with some surprise?). The dead of SLT is just the dead of a feature..not the dead of the camera line
So what’s the goal of Sony? One of my best Sony sources that always shared correct info sent me a short sentence:
“The Alpha line is not going away. They are working on technology that will outshine the competitors for early release next year.”
He is a top source and in one year from now we will be able to see and touch the new Alpha Camera Generation. Trust SAR and that source…he always told me the truth! Spread the word!

But the most important thing is that they may put there something else, like the hot mirror; and more importantly, that hot mirror may be in the same slanted position as the current SLT mirror. This way the reflected IR is removed from the optical path. And then the IR absorption filter may also be glued onto the hot mirror, and would completely eliminate the problems with the sensor toppings internal reflections. And Sony actually applied for a patent describing the IR filter placed on the SLT mirror.
And then, having that IR filter in place of SLT mirror makes it possible to have the sensor sitting in an effectively sealed compartment.
Then there's another possibility - the mirror chamber doesn't have to be filled with air (empty), it may be filled with some dense optical medium having all the IR filter parts placed inside of chunk of solid matter or in some liquid. That could serve two purposes - push the diffraction limit farther, and also it would make the former mirror chamber depth smaller, thus helping to make the system thinner.
So there's a lot of opportunities they may think of; the question remains if they are going to use any of those.

They are making sensor components on a µm scale not an nm scale correct?
