Halo 3 has over 1.5 million U.S. pre-orders

IMO, I think it could hit 3m worldwide this week, give or take.

2.3-2.5m in the US, and 500k elsewhere, maybe more.

Japan should be 50k.

UK should be around 100-200k first week, I can't remember where H2 wound up at (but it did wind up with 600k or more there).
