Andrew - this seems pretty much like a mirrorless version of the A99 II, no? Obviously there are some incremental improvements (actually lets you use AF in video, better stabilization, etc.), but a lot of similarities: High MPs, 4k, log, 120fps in HD (praying that this is high quality), etc.
I would love to see where the A9 falls into this group. Full frame without the crop - hopefully similar to the 1Dx or Leica. Anyone have any thoughts?
