New Leaf got bumped down to #9 a few days ago due to Nintendo having it as a free game through Club Nintendo coins this month.  Noticed 3D Classics: Kirby's Adventure is down to 7 now after Mario vs DK: Minis March Again! passing it up. I expect New Leaf to pass Kirby's Adventure within a month and perhaps catch up to Mario vs DK in a few more months.  New Leaf has now passed Pushmo making it to #3 on 3DS downloads and back to #8 on all software.
