But even if those attach rates that you use in the OP are correct, they say nothing about when all these games are bought. If it is "front-loaded" during the launch period, then the 360 is at a dissadvantage in the comparison. Having attach rates for the 360 from last year would answer some questions. Though I guess those do not exist.Parl said:360 owners on average have purchased loads more games - but this is obvious because they've also had the console for MUCH longer. But the rate at which they buy games is fairly similar to the rate at which Wii and PS3 owners buy games.
So, once the Wii install base equals the 360 install base in US (if it does), total software sales for each console, on a month on month basis, will be fairly similar if current rates continue big games releases will tip the balance though).
And if Wii maintains its software buy rate relative to 360 if it overtakes 360 in install-base (which most believe it will), Wii software will be selling more on average each month.
Before me doing this, I thought PS3 software sales were poor, even when compared to how many units it has sold, but this isn't really the case.
My point is the numbers only show a small picture, as have already been pointed out a few times. And they do not show the current "buy rate" at all (this should be the most interesting part).
