I calculated games sold per console for the Wii, PS3, and Xbox 360 13 months after their respective launches (for Wii and PS3: Nov 2006-Dec 2007, for Xbox 360: Nov 2005-Dec 2006). I used the monthly totals of America, Japan, and the two combined. Here are the data:
Xbox 360:
| Software | Hardware | Attach Rate | |
| America | 26,061,740 | 5,083,263 | 5.126970609 |
| Japan | 894,370 | 285,314 | 3.134686696 |
| Total | 26,956,110 | 5,368,577 | 5.021090319 |
Wii:
| Software | Hardware | Attach Rate | |
| America | 42,117,249 | 8,453,007 | 4.982516754 |
| Japan | 13,913,994 | 4,640,392 | 2.998452286 |
| Total | 56,031,243 | 13,093,399 | 4.279350457 |
PS3:
| Software | Hardware | Attach Rate | |
| America | 16,691,699 | 3,473,514 | 4.805421541 |
| Japan | 3,456,276 | 1,691,217 | 2.043662049 |
| Total | 20,147,975 | 5,164,731 | 3.901069581 |
I don't know if this has been posted before (usually I see the attach ratio for the consoles to date, instead of from launch), and even if it has, I am pretty sure it hasn't been done with the December data yet.
PS: This includes all bundles (Wii Sports, Wii Play, Motorstorm, any others). I just directly took the data from this site, which includes bundles.
Systems owned: Nintendo 64, GameCube, Xbox 360, Atari 7800, Genesis, PlayStation, Dreamcast, Game Boy Advance, Nintendo DS.
Year-end predictions (April 6, 2008):

- Wii: 46 million (44.4)
- PSP: 45 million (43.6)
- X360: 27 million (27.3)
- PS3: 24 million (19.4)
- PS2: 124 million (123.7)
