I bet it won't come until next year at this time. Sony will be updating their A7R III this fall and won't want to compete with themselves. Canon will likely release their new flagship hybrid camera then and it will probably have some crazy features, just like the 1DC and 1DX ii had when they released. I think if they make the A7S III have internal (6K Sensor) 4K 4:2:2 10-bit, with the venice color science, they will have an industry leading camera.
