I thought that 189.7 million number was shipped? How is that even comparable to what NPD reports for the 360? Shipped vs sold, NA vs. world,...
The chart below shows the attach rate according to VGC numbers for each console as of the first week of August of each year, plus how much it increased from the last year.
| X360 | increase | PS3 | increase | |
| 2006 | 2.97 | 2.97 | ~ | ~ |
| 2007 | 4.12 | 1.15 | 2.05 | 2.05 |
| 2008 | 6.68 | 2.56 | 4.57 | 2.52 |
| 2009 | 7.79 | 1.11 | 6.24 | 1.67 |
From this we can see that the PS3 did indeed gain .56 games sold per console on the 360 since last August, but we can also see that there are no definite, observable trends, so where it will be at next year is anybody's best guess.
