The EDELWEISS-II experiment uses cryogenic heat-and-ionization detectors in order to detect the rare interactions from possible WIMP dark matter particles on Germanium nuclei .
Recently , new-generation detectors with an interleaved electrode geometry were developped and validated , enabling an outstanding rejection of gamma-rays and surface interactions .
We present here preliminary results of a one-year WIMP search carried out with ten of such detectors in the Laboratoire Souterrain de Modane .
A sensitivity to the spin-independent WIMP-nucleon cross-section of 5 \times 10 ^ { -8 } pb was achieved using a 322 kg \cdot days effective exposure .
We also present the current status of the experiment and prospects to improve the present sensitivity by an order of magnitude in the near future .
