This reminds me of one of those comics you'd find in a newspaper where someone complains a treadmill isn't helping them lose weight, and it cuts to a bunch of boxes on it.
Either way, it's a horriblely designed study, If you play with just the wrsit flicks i'd be surprised if you lost anymore weight then a 360.
If you treat it like it's a 1 to 1 machine.... Then you do lose some weight on SOME games.
Not that it matters, I doubt anyone is buying the Wii to lose weight (well until Wii Fit comes out.)
People are mostly buying it because it's a dedicated game machine that plays games in a new way and is cheap.
Not to mention the flaws in the studys design.
Try lifting a barbell once an hour... vs lifting a barbel 24 times in a row... see which has better results.
