360 has higher attach rate

True, but not that important. Attach rate goes up with time as console owners of old accumulate games, and the 360 had a full year-to-fifteen months headstart over the PS3. Putting in a few numbers we can calculate the average number of games bought per console per week of ownership, calculated as 2*attach ratio/weeks:


November 22nd, 2005    225w        10.76  ->     0.095 sales/(console*week)
November 17th, 2006    175w        8.78    ->     0.100 sales/(console*week)


December 2nd, 2005    224w        5.96    ->    0.053 sales/(console*week)
March 23rd, 2007         156w        6.12    ->    0.078 sales/(console*week)


December 10th, 2005    223w        5.29   ->     0.047 sales/(console*week)
November 11th, 2006    176w        3.91   ->    0.044 sales/(console*week)


If I publish a new game today, this number is more relevant to project future sales for each region and platform than the "naked" attach rate, again because the attach rate is an historic total but not an estimate of the current sale speed. The numbers show that on average I can expect slightly better future sales per install base console on the PS3 in America, and quite better in Others. In the end the conclusion is that if sales are lower then you'd better blame the install base than the like of attach or tie ratios.

NB: this number is -of course- an incredibly rough average over all software sales, especially useless when we talk of big hitting exclusives, but still not more so that the attach rate and actually more statistically meaningful.

That post of mine is probably the most quoted thing I've ever posted.......but yesterday morning, I wasn't quite myself.  I made a few posts that didn't really have much thought behind them at all........
