Let's look at the present, not just the cumulative results of the past.
The 3DS is down by a dangerous amount yoy.
In Jan 2013 it averaged 220k per week. In 2014 it averaged 139k per week.
In Feb 2013 it averaged 186k per week. So far in Feb 2014 it's averaged 132k per week, and that number should only drop with next weeks data.
Let's break it down per region.
US
Jan 33k, 34k
Feb 41k, 40k
Europe
Jan 44k, 46k
Feb 34k, 40k
Japan
Jan 128k, 47k
Feb 97k, 40k
The west is steady yoy, but Japan is crazy low. Even comparing the full year of 2013 to 2012 shows this. In the west the 3DS sold about a million more in 2013 than 2012, but in Japan it dropped by about half a million. The system had great sales in Japan, but at the moment it seems to be the most troubled region.
