If you've read the latest Steam news, seems valve will be releasing a new DM map. Apparently they haven't decided the winner of the HL2DM mapping contest (which makes me a bit angry)
Is it my imagination, but doesnt this map look like a remake of datacore from HLDM??? I know the textures and lighting have nothing to do, but I've recognised the layout in these screenshots. See for yourselves:
