So now that PS3 overtaking 360 is a matter of weeks, how long until it reaches Wii?

How much did the PS1 sell after PS2 came out? I know PS2 sold like crazy still after the PS3 but I think PS2 was a phenomenon that may never be matched again. So how about the lesser (but still very impressive) PS1? I think that would be a more appropriate comparison.
