Considering the PS2 Dvd-rom players die right at 1 year, and you can't buy replacement Dvd-roms that are compatible. No wonder Sony sold so many. I do have to admit, it was a very good console to game with. But Microsoft took a lot of wind out of their sales with the highly modifiable Xbox.
Then the 360 got released way before the PS3, and the 360 was way cheaper, better graphics, and a crap load of game releases hit the market. The PS3 is still plagued with coding challenges and game manufactures are staying away from it like the plauge.
