Two weeks from now is the best bet, based on the Wii selling 260k units for the week ending 7/15 and probably a similar number to that this past week (159k without Japanese sales at the moment). Mario Strikers Charged in America and Mario Party 8 in Japan should at least keep that constant. EDIT: Considering that Japanese sales have yet to be factored in (which I just mentioned *facepalm*), almost certainly in two weeks - August 4/5.
