the songs sold nicely follows a 2nd degree polynomial. the formula on the chart is a little off, it's the weird math excel does with the dates.
with days since april 28, 2003, the fit is:
songs sold = 0.0006*days^2 - 0.0549*days + 3.7629
projected numbers:
MWSF (1/12/05?): 215 million
2 year anniversary (4/28/2005): 300 million
WWDC '05 (7/10/05?): 360 million
end of the year 2005: 550 million
i doubt this projection will even hold for MWSF...
