There's still daylight between attach rates for market leader Xbox 360, and those on PlayStation 3 and Wii. But the margin is narrowing.

A couple of reasons for this. One, many people buy the PS3 as a Blu-ray player/media hub. Two, the Xbox 360 being cheaper perhaps means that people buy a couple of (also cheaper) games with it when they buy consoles.
