how do you figure they're in a better place and have more units. The numbers they're saying they're going to have on launch day are the same if not worse for the numbers of Xbox360s in the same regions on its launch day, and the Xbox360 was a world wide launch so there were more sold elseware. I wouldnt go so far to say "a lot more mature" either, and i dont believe there was an unscheduled delay, but rather overzelous Sony PR to blame for that launch schedule confusion. Hardware wasnt even finalized, including core chips, until ~6 months ago so i fail to see where there was a delay, not like they could of launched but didnt. More like they had no idea what they were actually doing back in E3 05 and ready to say anything to throw a wrench into the Xbox360 launch.
"we'll have our console in spring!"
"oh sorry guys we dont actually have a console design finalized yet, we were just talking out of our asses, maybe in half a year"
delay? riiiight. As far as i'm concerned the PlayStation 3 is launching right when it could, there was never a chance before, and it could even use more time for supply build up too, but they cant risk losing the holiday sales.
