I agree that a true global shutter this isn't. However, it could be down to F5 territory (5ms I believe?) in S35 mode. I'm very curious to see what the IQ is like with the full 135 sensor. Sony says it used in sensor binning which (in theory) is better than line skipping. Could have some aliasing but shouldn't have much moire. Personally I'd rather see a 24mp camera  with a true global shutter, full 6k readout down sampled to 4k, and faster FPS/focusing but this is quite the camera.

But downscaling 8K to 4K requires a lot more horsepower of course, since it is four times the data...
Also it means you need a sensor that can do full pixel readout at very high speed.
Here's a list of Sony sensors with some specs: http://www.sony.net/Products/SC-HP/IS/sensor2/products/index.html
You can see the IMX094 (36MP fullframe) for example, as used in the Nikon D800 / Sony A7R. Max Frame Rate @All pixels = 4,7 fps.
Speeds are going up though. The current Sony 24MP asp-c sensor (IMX193) does 8.7 fps. There's a new one listed (IMX271) that is rated at 19 fps. Maybe this could be used for 4K with a small crop or little processing. Sadly the 12MP 35mm Sony sensor is not listed, would be interesting to know the max frame rate of that one.
