You should include lasped_gamer's analysis that the average 360 is played 10% more than the Wii, and the PS3 3% more than the 360. You should also replace the term "average console owner" with "average console user," since the Nielsen report describes them as user numbers rather than owner numbers.
User averages can be extremely misleading. Having more than one person in a household playing games ends up looking like a weakness if that person only spends a small amount of time gaming. For example, a Wii household with a main user playing 10 hours a week and a second user playing one hour a week looks worse than a single PS3 gamer playing 11 hours a week, even though the PS3 user is only gaming 10% more than the main Wii user and both consoles are being used just as much. The result looks the same as your average user analysis: The average Wii user plays half as much.
"The worst part about these reviews is they are [subjective]--and their scores often depend on how drunk you got the media at a Street Fighter event." — Mona Hamilton, Capcom Senior VP of Marketing
