Software sales follow install base, not monthly hardware sales. People that buy a new PS3 aren't going to just go out and buy 7 games off the bat, they will gradually purchase games.
It will take probably until the 360 and PS3 install bases are the same before weekly game sales of the two are consistently equal, and even longer for total PS3 game sales to equal 360 due to the > 1 year head start it had.
