why the psp is dead/dying and DS reins supreme

1 reason only:

portable game dev time.  companies are given much shorter time on a prtable game than a console game...this is bad for the psp because it is capable of making near ps2 graphics, but devs arent given the time to exploit that. (exceptions are mgs and gta)

on the ds, however, the hardware, while technically inferior, lets devs put the shorter dev time to make a proportionally better game. 

I think it's because Nintendo actually concentrates on the games,unlike Sony.

I agree that DS is reigning supreme, as they should. They are succesfully expanding the market, and allowing more types of people to become gamers.

BUT PSP is not dead, nor is it dying. It's selling pretty well actually, 20 Milllion in 2 years is good sales numbers no matter how you look at it. 

How is the psp dead/Dying????? last i heard the psp was still selling well and alot of good games are being made for it.Ryan0_1

I still think it is all about the price. It makes for a wide variety of people to afford it, it comes in cool colors and counting gba games the library is like 1000000000000000 titles.Cpt_Apollo
