It seems like this game may have been lost in the shuffle, but it still looks like this game should be around at least 1.2 million sales judging by the fact that sales of CoD3 in the US sit around 675,204 and adding on PAL regions, which as stated before usually equal or surpass US CoD sales, this game should be around 1.2 million, possible 1.4 if CoD3 continues to sell well in the US (I expect it to top out at around a little over 700,000 in the US). This stock is undervalued at the current price.
