Nauticam took a wait and see approach to X-T2 demand, monitoring requests before deciding whether or not to produce the housing. In the end there was sufficient demand, and this will be rolling out in the next few weeks.
I have to admit it is really frustrating for manufacturers to do this.. I would have happily placed a pre-order as soon as the camera came out if they offered that option.. I have been fighting jumping the canon ship for awhile and i love my fuji x-pro1..
the lack of housings for canon's mirror less line and fuji's stinks, hope to see this happen really soon even though it will likely cost me a bunch of money.
