So we're expecting Halo itself to push the 360 past the Wii when it can only sell well in 1 region, versus 3 for the wii?
The Wii is less than a million behind the 360 in Europe as it is.
Nintendo's best strategy for September is to push a bunch of non-shooter games, both core and non-core titles. We already know Battallion Wars 2 is due the day before Halo 2, so I'd put up MySims and a few other appealing titles to get the attention of all of the gamers who don't care for Halo, and heavily advertise them. :)
Of course, a couple extra shipments of hardware to North America would help too. ;)
Nobody is crazy enough to accuse me of being sane.
