"This took a huge chunk out of the profits Sony garnered from its own software sales and licensing fees. "
There are two additional small things.
First the PSP which is Sonys first ever handheld, so you can add its development and launch costs to the profit of the gaming division if you want to know how much money the PS2 made them. (It will be many hundreds of millions or billions by itself)
Secondly 2 billion 2000 are (for a public traded company) almost 4 billion 2008 because they expect a return on investment of 8%.
So the PS2 made them much more money than you implied.
