Those are still pretty horrible sales for the Wii U, but I'm glad DKC wasn't a full on flop as its one of my top 5 Nintendo IP. Hopefully it can kick/scratch/claw its way to 500k in the US.
The GameCube sold 165k for Febuary 2003 (the corresponding month), so Wii U is still way behind the GCN and the gap is not looking to close any time soon.
