I've tried to find the thread, but no luck so far.
As I understood AJ's comment or explaination, it is about the hardware,
and that Audya is capable to things in another way than SD9.
But I don't think he mentioned anything about a new Audya successor ...
Maybe AJ will post something about it in this thread if / when he see it?

Btw,
Genos is not a new T5, but more like a T6.
