I thought it would be interesting to look at the weekly attach rate for each console. It won't take the weekly sales of hardware into account, as that fluctuates too wildly at times. It will look at purely weekly software sales compared to the total install base.
Week 1: Ending 2nd January 2010
| Console | Weekly Software | Total Install Base | Weekly Attach Rate |
| Nintendo Wii | 7,704,153 | 65,648,466 | 0.1173 |
| Sony PlayStation 3 | 2,906,710 | 30,946,800 | 0.0939 |
| Microsoft Xbox 360 | 3,397,756 | 37,047,408 | 0.0917 |
| Nintendo DS | 4,565,985 | 124,470,583 | 0.0367 |
