The Wii has taken the record for best home console Black Friday week sales even without Japan in.
The DS broke the record last year with sales of 2,012,422: http://vgchartz.com/hwlaunch.php?cons1=DS®1=All&cons2=PS2®2=All&cons3=Wii®3=All&weeks=175&weekly=1
But for home consoles it stands at PS2 with 1,761,665.
We'll probably see the first 1M+ sales in a single week for a single territory by either the DS or Wii by Christmas-peak though.
