550k Wii U would be a pleasant surprise, but I doubt it.
It would explain the strong software sales.
US software sales according to vgchartz:
Wii U: 2,213,110
X1: 1,904,622
PS4: 1,837,965
How is the accuracy of software sales at vgchartz compared to hardware sales?
I guess hardware is more reliable.
EDIT: Ah, Mario + Luigi Pack counts as 2 games, that explains a lot.
