Mario & Luigi RPG 3 (3432) has now sold more than either previous game sold while in the Top 30, and has yet to drop from the Top 10.
One Piece Unlimited Cruise: Episode 2 is performing similarly to the original. Its first week was lower, but its second and third weeks have been better.
Animal Crossing City Folk has finally fallen out of the Top 30 (for this week, at least), but Wild World at #25 maintains an Animal Crossing presence in the list. At the rate it's been selling recently, Wild World is probably 8 or 9 weeks from hitting 5 million.
