Gran Turismo 5:

Halo 4:

Aligned launch chart:

As you can see, Halo 4 is at 5,158,526 after 3 weeks on sale and is currently tracking 1,409,923 ahead of Gran Turismo 5. Interestingly, Gran Turismo 5 sold more in its 3rd week on sale than Halo 4 did (672,202 and 607,817 respectively...So GT5 sold 64,385 more). However, this is explained by the fact that GT5 launched at the peak if the Christmas sales period and subsequently followed different sales trends than Halo 4 will.
According to my Halo 4 predicted sales chartz thread, Halo 4 should sell 395,200 worldwide next week.








My prediction threads:
Wii U will sell under 40m units (made on 14th September 2012)
PS Vita will sell under 20m units (made on 30th September 2012)
Wii U will sell under 7m in 2013 - I was right
