Exactly and if you take this into account, PS3 owners roughly buy just as many games per year as 360 owners do.
The PS3 install base has been and will be catching up with the 360 significantly this year.
The average months of PS3 ownership will go up, but will probably never reach 360 levels because I expect 360 sales to slow next year and PS3 sales to considerably pick up. So there will be a continued stream of new PS3 owners keeping the average months of ownership down.
Ideally the PS3's average months of ownership will go down, as this in effect means a hell of a lot new consumers are buying a PS3.
