Yes I have missed it. Sorry.
But if you dont have the data for PS1 you cant make conclusions just because of Japan its a completly different market. Not comparable to the rest of the World.
You can see here

That the PS3 and the PS2 are not extremly far away. The difference is under 40% and if you subtract those 40% from 138 Mio you get a bigger number then 60 Mio.
The whole data comparison is worthless. because this situation is unique nothing is like in the previous generations. And because of the PS1 if you have data we can talk about it but i remember I read something even here which said that the PS1 and PS3 had pretty similar sales I will search for it.
