There has been a lot of interest and uncertainty about Craft Camera lately. See their webpage for more information about their newly announced camera.
Very importantly, note the following statement on their website:
Full technical specifications will be announced early this summer.
They do appear to be offering a 4K sensor with global shutter and 60P. Let us hope they can deliver.
It costs $500 to reserve the camera and they claim to be shipping in late 2016.
