What is most important to note here is that those numbers only account for Xbox 360 sales. I was unable to find out how many copies of the "Orange Box" were sold on Steam (sans box).
Rounding out the rest of the top 5 for the week ending October 13, 2007 we have:
Pos | Console | Game Title | Weeks on chart | Sales for Week | Total Sales |
1 | 360 | Half-Life 2: The Orange Box | 1 | 348,049 | 348,049 |
2 | 360 | Halo 3 | 3 | 285,860 | 3,482,376 |
3 | DS | The Legend of Zelda: Phantom Hourglass | 2 | 144,474 | 493,444 |
4 | PSP | Final Fantasy Tactics: The Lion War | 1 | 89,412 | 89,412 |
5 | Wii | Wii Sports | 47 | 88,843 | 5,185,648 |
I know what you are thinking, "Wii Sports???" Well, it comes bundled with every Wii sold so you have to expect that it will be on the charts for as long as it continues to be bundled.
Speaking of the Wii take a look at this chart where launch dates are synchronized.

Not even a year and the Wii is way ahead of everyone. The PS3 looks to be on track in as much as the Xbox 360 was on track during its initial launch cycle. For those who say the PS3 is a failure do you also consider the Xbox 360 a failure? According to the chart the PS3 is on a nearly identical sales trajectory as the Xbox 360.
The only winner is the Wii. You know, that gimmicky console that so many people thought would fail while others just called it a Game Cube in a white box. Not everyone who plays video games wants to play an FPS game nor do they want to play games online, some people just want to play games to have fun. Imagine that?
