The game has not had an easy path to retail and with mediocre review scores we expect sales to drop away fairly quickly. With that said and the holidays fast-approaching, we are expecting around 3.5 - 4.0 million units sold-through by the year end. Of the 1.4 million, 52% of sales were on Xbox 360, 43% on PS3 and the remainder on PC. The Americas accounted for nearly 2/3 of sales (exaggerated slightly by the staggered release dates)."
