PS2's highest one-week total was 1,775,427 according to here(week ending 12/23/02) with 1,471,073 units sold the week prior. The DS will likely end with around 1,640,000 for the week ending 12/15/07. If both supply and demand exists to see the same gain(either absolute or relative) the DS would still be short of 2 million for the week ending 12/22/07.
