I was gonna say that PS2 was the hardest piece of hardware to work on due to the Emotion Engine, but others beat me to it. Also let's take a time-travel:
Saturn was harder to develop and more powerful (than PSX) and lost.
PS2 was harder to develop for and smashed the competition (while being the less powerful).
PS3 is the hardest to develop for and the most powerful one.
Another Saturn? I don't think so, but only time can tell.
