I'm starting to think 3DS is not even going to reach 70 million LTD, sales are fading out quickly, I think maybe they'll hit 5.5 million 3DS shipments next year and after that it will get really slow.
Looks like 3DS will finish somewhere along the lines of 68-70 mill and Wii U at maaaaybe 16.5-17 million for their life time sales at this rate.
