i have contacted cascable several times, i am sure they are a small crew and they do support a lot of cameras....
it comes down to what wants to achieve.....
full raw workflow straight into a solid DAM? hardwired tether to either a laptop or PC tablet into LR.....works great, fast, available right now....
wireless raw wont work for a while because the data is just too much and connection are too slow.....for now, who knows what the future holds, but regardless, it will be a while....
jpeg "workflow" for preview and quick distribution...this should work fine over wifi with existing fuji app....
wired tether to iPad...yes, we all want it, but apple wont let us have it....and not just us, the data port on iOs devices is locked off....to anyone other then apple....dont see this changing anytime soon.....
i have been thinking of getting a surface just to run LR on it for wired tethering....
there is this article on tethering (as well as a mobile workflow) with the X1D....it seems like an advertisement but i am sure it more or less should work like he says it does, and i think the newer surface(s) are cheaper and faster, so i dont see why it shouldnt work.....and once LR is running, there should not be too much difference between that and an iPad....
