OOT3D has a bundle and no competition in the RPG or Advanture genre and the 3DS is selling well while Wii is well 400k behind this week.

Skyward Sword is selling better then Twlight Princess really

Twlight Princess Skyward Sword
716,111 978,010
263,673 300,572
205,952 310,794
186,546 281,228

So it's selling fine nothing wrong with it yet.

TP was a launch title you can't compare. Following this path SS will have trouble to do 60% of TP.
