i think it might be possible, if the PS3 keeps getting great Japanese games like Persona 5, Tales games, Ars no surge etc... for some year (3 or more).
anyway the PS3 deserves a lot of respect,
-coming out 1 year after the 360.
-100 bucks more expensive
-with a bad marketing campaign
-A horrible pre launch E3
-the "worst" version of multiplats (at least at the beginning right now they are pretty much identical),
-And with very few games
and even then it still competed really well with the 360, to the point that we officially don't know if it has outsold it now or not due to the lack of official info, but i guess most people out there have no doubt that it will outsell it (if it hasn't already), add to that the great first party support and the enormous amount of exclusives that it got (and its still getting) and well... its a great console.
