The other one sounds like it is going to be mirrorless and wear an A-mount, (again if true) and if so it remains to be seen how the backward compatibility stacks up, everyone who has invested lots of money in expensive A-mount lenses will be watching that one closely.

It seems pretty obvious to me -- if Sony improves the on-sensor PDAF enough to be as good as traditional PDAF, they can finally drop the mirror. This simplifies the design of the camera, saving money.
Despite claims that Sony has no plans for the future, I suspect that this has been their goal for years. SLT was just a necessary first-step in this direction.
I guess we'll have to see.
Well yes it seems that Sony would like to build a mirrorless A-mount (if you can call a mirrorless A-mount an A-mount, an SLT isn’t strictly an A-mount either) but the problem with on chip PDAF is keeping it working with A-mount lenses …all of them and doing it without affecting performance, they haven’t done that yet.
If they kiss goodbye to all screw drive lenses they might do it, they got rid of the i-shoe so I guess they could scrap screw drive AF too, perhaps Sony assessed that whatever repercussions that happened from ditching the i-shoe were acceptable, and doing the same with screw drive lenses won’t be much worse…but it will be.
They might initially test the waters with an A-mount mirrorless without screw drive AF but with enough other advancements to bedazzle enough people alongside another more regular DSLT, just like they did when phasing out the DSLR.
Ok say they do bring an A-mount mirrorless, so what? All they have done then is build a larger version of the E-mount, one with a large empty space in front of the sensor (that doesn’t have screw drive most likely) and what does that achieve? You then have an E-mount doing E-mount stuff, and an A-mount doing E-mount stuff too, but not as well because it can’t use E-mount lenses or any other lenses apart from A-mount lenses, (and most likely only some A-mount lenses) whereas the reverse is true.
The E-mount is not a full system, and neither is the A-mount, there are lenses and accessories missing from both, gaps that should have been addressed long ago in the case of the A-mount so that it would become a convincing system.
It doesn’t appear to matter that the E-mount isn’t a complete system as it seems that users are happy with it the way it is, and putting up with the adaptors.
Sony were never going to challenge Canon or Nikon making a haphazard half system here and a half system there with an incomplete accessory list including at least one that doesn’t work properly and then repeat that unsuccessful tactic by doing it yet again with an even smaller incomplete system such as with the FE mount.
So no their object wasn’t to always build a mirrorless A-mount it was to gain the expertise to build the E-mount, I have no idea what the future is for the A-mount (or what’s left of it) and maybe Sony doesn’t know either, but it’s not looking too bright.
