Top:
-Luigi's Mansion: Dark Moon: a 300k units debut is not something many games have had lately. Luigi is not Mario, and this is not an holiday period, but still it opened doubling the last Paper Mario. Also, the strength of the IP was unproven because the last, and only, entry dates back to 12 years ago. So incredible result, it will cross half a million easily.
-Vita hardware: nice hold for Vita, indeed. I expected it would have sold less this week. It also got 4 games, so that's well explained.
Flop:
-One Piece: it sold less than half of what the previous one did. Bad word of mouth probably, since apparently the game was not so good.
-Dead or Alive 5 Plus: the series is really declining. 5 did not do so hot either, but it's weird to see now Dimensions revaluated, since back then it was considered a flop while now, with it almost 50k units, it can be considered an average performance.
-Soul Sacrifice/ it seems Inafune's game is not having legs at all. Well, for me it was expected, but many people thought it was the game to sell Vita. Apprently, it's not outside the launch week.
