This was just GameFly and GameCrazy changing dates.
A) GameFly might actually delay it a month in order to stock up for massive rentals...as they're just a rental service, not a store.
B) GameCrazy might have followed suit, because they're dumb.
Anyway, even if it is true, it had BETTER NOT be the end of March, that's waaaay too long after the Japan launch to make sense or to keep us from going crazy across the sea.
Early March? I could cope...but I don't really believe it'll happen. A week or two at most.
