no, the 5.6 million is accurate, this was the number of consoles the 360 had sold when the ps3 entered the market so after those units why should the time argument bare any meaning if every console from there on was sold in the same timeframe, therefore having the same ownership lifetime. The 2million is rough i agree, but thats because i was to lazy to look at the release dates on all regions for the ps3 and see how large the gap was in those regions when the ps3 entered the market in those regions. In any case the number won't be large by any stretch of the imagination, these regions for the most part had less than 1 year in release in favor of the 360 over the ps3 and some of the regions are smaller markets.

Total attach rate will always increase with time.  That is why time is an important consideration.  Also, every console from then on was NOT sold in the same time frame.  The 360 and PS3 sold at different rates for a long time, which will affect the rate of software adoption.

The best way to look at it is on a week by week basis.  As of a few weeks ago the average PS3 owner bought a game every 9.47 weeks and the average 360 owner bought a game every 9.75 weeks.  It is close, but PS3 owners are actually buying software at a faster rate than 360 owners.
