This makes me believe that I will eventually HAVE to purchase (and

Of course Troy could complete the existing lucida mkiv vectors in

We just purchased the OTF versions. I'd rather have TeX developers
focus on getting OTF support right than preserving legacy capabilities.
In luatex we're 'mostly' compatible with the old tex engine but as
opentype math support is more advanced, the focus is on supporting that
as good as possible. Also, as opentype math originates at MS/word with
cambria as benchmark that's mostly setting the baseline.
Of course, in context mkiv we can go a bit beyond that (and there is
already some in place). We can also
For years we have been able to format old docs with current TeX
systems. Now I just
hope the old docs will work without too many changes using OTF versions
of the fonts.
In principle regular math should work ok. At some point we might benefit
from the opening up of math parameters (quite some was hard coded in the
traditional tex engine, much has been moved to the font parameters and
luatex also provides more control).
Some constructs (like radicals and accents) are more native now and less
depend on macro magic.
There will never be full visual compatibility, if only because open type
doesn't have the (dimensional) limits of tfm (that made sense at the
time).
