Oh man, you tell me. It's probably like the A350 - great at lower ISOs, but iffy at higher ones.
It would be interesting if Nikon releases a D3x using the same sensor with better performance at ISO 1600 up. Sony really does tend to overdo their noise reduction, hence the seemingly watercolor effect.
Kudos to Sony, though, for still being able to make in-body stabilization work with FF. There were a lot of rumblings that it couldn't be done, since there's no more extra space to move an FF sensor. Or something.
