About 40 million PS2 owners in the United States.

That would mean for the US ~78% of PS3 owners also own a PS2,
~66% of Wii owners own a PS2,
~67% of 360 owners own a PS2.

Interesting, anyone happen to know the PS2 user base in the US according to NPD? Using NPD numbers is best since this is NPD polling.

For now I will use VGC #'s which have NA at 48.45m PS2 owners and an estimated 43.61m PS2 users in the US. Therefor in the US:

8.29m PS2 owners have a Wii or about 61.30% of Wii owners.
7,85m PS2 owners have a 360 or about 64.12% of 360 owners.
4.36m PS2 owners have a PS3 or about 78.61% of PS3 owners.

The Wii accounts for 40.43% of upgrades*.
The 360 accounts for 38.30% of upgrades*.
The PS3 accounts for 21.28% of upgrades*.

*Where an "upgrade" is a console hardware purchase made by an existing PS2 owner.

The thing is that percentage of next gen owners who own a PS2 is only part of the picture.  Raw sales as well as overlap are important as well. Although there is nothing to base overlap on within this data unfortunately.
