It's down 30% year over year which isn't great.Seriosuly, everything has a huge drop, including the 3DS, because this week in each year is known for it, and people focus on the Wii U. Come on guys...
It's not gaining despite everything done while the Vita is up quite a bit year over year.
The 3DS, while somewhat concerning, has sold so much that it doesn't generate that much concern. It's also #1 by a long shot.
