bbsin, That's a nice update. Here's a graph for the same data a posted some time ago, albeit in Yen. The third graph shows profits in the PS2 era. 
ioi,
Could you put those figures (quarterlies of SCEI, Microsoft Entertainment and Nintendo) into a database on vgchartz, pretty please? Would be very useful.
bbsin,
You said that Nintendo made 40 % profit on hardware compared to software. That's not true. What you can see in financial report are revenues, not profits. You assume that the Wii has 20 % margin (which you can't prove by the way). Nintendo's overall operating profit is above 20 % however. Therefore software margin will be better and total software profits will be just as big as total hardware profits.
Hardcore gaming is a bubble economy blown up by Microsoft's $7 $6 billion losses.
