It definitely pushes some 360 owners to Windows Phone, but I don't know if it's all that many in the end. I mean, statistically relevant in the grand scheme of things. If makes a dent, for sure, but I'm not sure if it's huge. With that said, I'm interested in getting a Windows Phone and I happen to be a 360 gamer. But I wouldn't say it's because of the fact that I own an Xbox 360. It plays a small role, but that's about it.
