We're talking America so this is not at all surprising..it's 360s market. And if you look at all the info, it actually doesn't necessarily mean that American 360 owners buy a lot more games than American ps3 owners; the number of games is almost identical. In America, 360 has sold ~20.5 million systems, while ps3 has sold ~11.8 million. So 360 has sold almost twice the number of systems in America than ps3 has. Two times more 360s in America than ps3=two times more software bought for 360 than ps3. Still a success, still money for MS, but not really a surprise.
