You aren't winning against sony fanboys.
Despite the fact that the 360 is winning, in their opinion its going to lose, even if it takes 10 years which is some reason okay and not in any way an indication that their system isn't as desired by your average consumer.
And even while the 360 is winning and selling the most copies of games you just get to hear about how much better the PS3 is, it does Blu Ray, it does... home. Why it does all kinds of things, and you own a stupid 360 which also happens to do all of those things except the debatably useless Blu Ray.
X-box fans have the best library of titles and exclusives so Sony fans grab the few first party games they get and elevate them into greatness. (Heavinly Sword anyone?) Even if they are lacking games, which I'm not saying they are, they are going to take whatever they have and sing its praises to the sky.
Basically if Sony could drag everyone of its fans into an alley and rape them, in the end the bloody sony fans would come out and tell you how wonderfull Sony is.
So if we win we lose, if we lose we lose. It doesn't really matter, you are not going to stop Sony fans from claiming victory.
