Wilhelm Research has all the latest data on printers with stable
inksets <http://www.wilhelm-research.com/>.  The "on display"
estimates are only that, but they are basically relative to each
other.  Note that Wilhelm has begun testing 3rd party papers using the
three stable inksets; see the middle column.  

The estimates for good materials range from 65 to 200 years on display
at 450 lux until there is a 20% loss in at least one dye.  This is far
superior to standard chromogenic prints, even Dye Transfer prints,
which were said to be stable for about 200 years in storage.  The
distinction is that this estimates was for dark storage; the
recommended type of storage.  

Mark McCormick-Goodhart has started another Image Permanence Research
website, Aardenburg Imaging and Archives

0.  The previous URL lists the papers tested thus far.  For a modest
yearly fee he will test a paper and ink combination if it will help
the other members.
