One would hope they included it but seeing as it hasn't happened for the GLD yet I wouldn't hold my breath.
In addition to that, I highly doubt that they will use any adat expansion on any of their consoles other than on the by using the MMO Card which has 24 Adat output but no inputs. Adat is pretty much obsolete considering all the digital snake/stage box options on today's consoles.
I heard that the initial design had no expansion card slot at all. That could have changed.
I am really hoping it will be compatible with my GLD stage boxes! If it were to have maybe 16 local inputs and the ability to use an AR2412 that would be awesome.
