I  see that under the Inspire 2 Page it says that "An all-new handheld  camera mount is compatible with the Zenmuse X4S and the Zenmuse X5S,"  does anyone have an idea of when this will be released?

"Ground Filming"

"An  all-new handheld camera mount is compatible with the Zenmuse X4S and  the Zenmuse X5S, bringing these cameras down to the ground for more  flexible filmmaking."
