As we've been preaching for some time, the Wii has a much lower attach rate than other consoles (that's the magic number of games-per-console consumers buy). We often tried to explain to one of our Nintendo-loving colleagues that even tough the Wii has sold more systems than other consoles, it wasn't as big a moneymaker for Nintendo as one might think, because the real profit comes from $50-60 games, not a low-profit-margin box of hardware that sells for close to what it cost to make.

Now the New York Times is confirming our suspicions, pointing out today that, "The average Wii owner buys only 3.7 games a year, compared with 4.7 for Xbox 360 owners and 4.6 for PlayStation 3 owners." The Times goes on to say that Super Smash Brothers Brawl sold more than 1.4 million copies its first week, but, "sales dropped more than 90 percent over the first four weeks.

It'll take a lot more than that to sink the super-popular Wii -- but take a survey of your Wii-owning friends who aren't typical gamers and see if they regularly buy new games, or if they're just happy to play Wii Sports over and over again -- the answer may surprise you.
