425k week one? It should do at least 600k week on in the Americas alone, if not more. Total WW pre-orders right now are over 1 million. It hit 250k in JP/US last week, and EU pre-orders were already totalling more than 500k.
From reading various gaming sites and news sites, I'd say pre-orders are likely to hit 1.25-1.5 million right before release. The game should open to about 2m week one, if not more. PS3 numbers should jump by 250k from GT5 bundles alone, not to mention others who are going to buy a PS3 just to play GT5.
Sales should hit 4-5 million no more than a week into January (think gift card cashouts).
