The console is such a huge seller the past demand for it probably resulted in significant investment in production technology, they sony are probably selling them at a profit in spite of the apparent low price.
I suspect MS probably terminated the Old Xbox to make room for the 360 in the same facility.
Anyway the PSP is basically a portable PS2 so PS2 technology (MIPS series CPU's and emotion engine derivative graphics set ) live on and all in a nutritious 200gram bar.
PS3 number 1 fan
