reverie on 24 May 2008
juryvicious,
I think Nintendo's graph refers to their fiscal years which run from April to March. The first bar is 11'06-03'07, the 2nd is 04'07-09'07, the 3rd is 10'07-03'08.
Viper1 probably looked up the quarterly reports at nintendo.co.jp and got the shipped software figures for those periods.
Hardcore gaming is a bubble economy blown up by Microsoft's $7 $6 billion losses.
