What did ps4 do in that time? Surprised Wii didn't do more.Both PS4 and Wii had little stock for the holiday... when you launch in the holiday that is what happens.
Insane attach rate for Mario though dang
When you have the holiday in the end like Wii U then you have stock issues in the start but you can build a big stock for holidays ending with better overall sales.
Just estimate how a PS4 or Wii could sell if they release in March and have big stock in the holiday.
PS4 for example sold only 1.8m in November + December 2013.
