Good find.

Was this as of end of February 2011?

what month are these numbers for?

Pretty sure these are February. Quite different from the USA Retail Preview. Wow at JD2! 260k more than expected! All other Wii titles shown here appear to be over 100k undertracked as well!

EDIT: Just checked, everything appears to be massively undertracked! Black Ops 360 has more sales than expected for Black Ops combined.

Appears to me that the phenomenal hardware rises this month weren't a fluke.

SW Last month obviously (KZ3, MvsC3??), Hardware LTD

Hm.  Interesting.

Looks like Vgchartz numbers are damn close for America's Lifetime totals.
