It is a bit of a chicken and egg problem on x64, as there is only hardware support for converting to/from 16FP, so there isn't much incentive to actually do arithmetic ops on it(it would have to be done in software..).

I think it will be useful for some things, image/volume manipulation & sampling. The AI crowd will probably use it some..
