Of course Modern Warfare 2 was going to have a huge second week drop. With things marketed for heavily hyped openings, sales past that rely on word of mouth and post hype marketing.
But these are the percentage drops for them and Modern Warfare Reflex:
MW2 (PS3) 81.71%
MW2 (360) 83.09%
MWR (Wii) 22.49%
Now if the other two have lower third week drops, they might have legs post opening. Just for this game, the low drop for a game with almost no marketing, and barely any shelf space compared to the other two, is really promising.
EDIT: Please Disregard This And Lock. I've Started A More General Thread For The Game's Sales.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
