Bingo. It was addressed well above, but I like to stick my nose in.
There's 2-3 of us around here with different cobbled-together versions of Dark*Matter running D20 systems.
If only WotC would listen to their market share ... y'know, me ... and totally re-release Dark*Matter. But alas, they did not, and I must make due.

[sarcasm]Of course they won't make Dark*Matter. Nobody wants that. Everybody who buys d20 Modern only wants to play D&D in the modern world, that's why Urban Arcana is the default setting, and the core rulebook includes Illithids and Displacer Beasts, but not Grey Aliens and Sasquatch (monsters that non-D&D gamers have actually heard of).
Since most people only want to play D&D in a modern day we'll aim toward that, but we don't want them to also have to buy the D&D books they probably already have, so we'll put plenty of reprinted D&D creatures, races, and an entirely copied magic system in the rulebooks.
They know that everyone really wants Complete Reprinted Splatbook or Printed Out Web Content Folio III instead of a suppliment that actually supports a popular old setting, or explores a gaming genre other than magical fantasy. Oh, and just to be sure, Paizo can get rid of all d20 Modern support in Dungeon, because everybody just wants D&D stuff anyway.

But seriously, too bad Dark*Matter is being left unused. There was a attempt at a conversion at Polyhedron, but it had a lot of gaps (like PrC's for Voodoo, Shamanism, Enochian, and Mindwalking FX at least, and stats for the Ekkimmu too, normal d20 Vampires just don't fit them at all). I just don't think that within the allowed page space they could get all the mechanics to play out the setting (even with most of the creatures and some organizations in the Menace Manual), that were needed and lay out the setting.
