Sony’s domination = How much profit?

Reverie,

                 I'm really grateful for your knowledge and input on all this.

I like the fact that you have narrowed down the gaming divisions of Sony and Microsoft’s respectfully.  It's a rather steep fall for Sony from the looks of your chart.

Considering that PS2 only made two billion, and I'm sure Sony lost more money attempting to get into the gaming market, I have a feeling they made less with Playstation than they did with PS2.

Especially since they seemed to introduce, at least effectively, significantly pricing their units lower than the actual production cost of their console hardware.
