Wedbush Morgan prophet Michael Pachter revealed in a recent statement that he believes the launch of Halo 3 has greatly driven Xbox 360 hardware sales for the month. Really now, who didn't see that coming? Aside from Reggie of course.
Furthermore, Pachter predicts Xbox 360 hardware sales for the month of September will surpass that of the Wii by at least 25,000 units. We'll know for sure soon enough, when the September NPD is released later this month.
