It seemed blatantly obvious that this was going to happen, when the game sold through more than 70% on its first day.
In the main sales thread for japan this week, people seemed to be saying that the game could still be classified as a bomb. (Weren't you saying that, Outlaw?) Which seemed strange to me, but I guess it could be classified as a different sort of bomb, one where retailers didn't want to buy enough initial copies to give the game chance. If that's what's going on here, than at least the game has convinced retailers they underestimated demand for it, even if it actually hasn't managed to sell enough copies at this point to be considered a success.
