The NY Times reported today that Zimmer Holdings obtained FDA approval for knee replacements specifically designed to more closely match women's anatomy. This is the first in a planned product line called Gender Solutions that will include "feminine hips and other artificial joints."
I don't know if this would include ADR but one of the issues for me with a 2-level cervical ADR is the question of whether my vertebra would be large enough to support a prosthesis above and below.
Also of interest, given Medicare's non-approval of ADR partly on the grounds of its not having been shown to be better than fusion, is that the article notes that Zimmer only had to demonstrate that their new prosthesis was not worse than other knee replacements.

"Not worse than other replacements?" Now that's a loft goal to motivate the troops?!!

Interesting post, though. To your question about endplate sizes -- I thought that the very wide range of Charite & ProDisc endplates got you covered? Pun intended...

Hopefully by the time I may need one of these devices that quote will state, "Much better than other replacements."

There may be some interesting developments over the next few years as this relates to artificial discs. We have seen evidence that subsidence of devices occurs more often in women because of differences in bone densities (at least anecdotally, as seen on this forum). This may account for differences in next generation designs, which have convex endplates. Alas, time and data will connect the dots…
