I just saw it not long ago - super awesome. Just wish I had the money for one.
Just a quick list of specs:
Full frame
24MP
4K/30fps
20fps RAW with autofocus
~240 RAW/~360 JPEG buffer
2 memory card slots
Bigger battery (approx. twice the battery life of current models)
~93% screen coverage for autofocus (can't remember how many points)
Touchscreen + joystick
Australian price is probably close to the $6000 mark (this is just my guess)
5 axis IBIS
It's a huge improvement over previous models, but they have marketed it towards sport photographers. Nevertheless, I'm sure many other type of photographers can benefit from this also.
