If it's not out already, it will be soon. I've seen one (i1 in a UV version
that is).
Personally, I'm not sure the whole UV thing is as big an issue as some make
it or maybe the i1 isn't as susceptable as some devices. Like I said, I've
made profiles with both a non-UV Eye-One AND a Spectroscan with the UV
filter mounted on some inkjet papers that will fluoresce under a blacklight
and I don't see the difference in the end result.

I think the UV thing will become a bigger issue when profiling tools
don't take the approach to UV of basically sticking their fingers in
their ears and saying lalalalala very loudly.
Paper fluorescence isn't really the big problem. Most profiling
tools, though, make the assumption that paper white is the brightest
thing they have to deal with, and they get very confused when
confronted with, say, a yellow ink with 160% reflectance. Filtering
the UV (either by taking it out of the light source or by filtering
before it reaches the sensor) may be an OK short-term solution,
particularly when we continue to use D50 (which has no appreciable UV
component) as our standard for evaluating reflective copy, but the
long-term solution has to be intrsuments that emit UV and detect the
response of the sample to UV, and software that knows what to do with
that info when it's fed to it.
