Honestly, I think you could have made that case a year ago, maybe even two. Now though, I don't see it. PS3 may have sped Blu Ray adoption slightly, but it's still a miniscule market. And now, whatever BluRay adoption benefit Sony gets from the PS3 is offset by the fact that consumers right now have cheaper options for BluRay players. Down the road Blu Ray should make Sony a lot of money, but right now, today, not only did it effectively kill the PS3 taking first place because of the necessarily higher price point, I don't think you can say it off set that by either being the piece that assured Blu Ray's format wars victory or that it has made Sony significantly more money by including it.
