I'd go by December 2010 but the idea is right. DS is less than 5m behind PS2 in the USA. It outsells it by at least 300,000/month most of the time now. November will see DS outsell PS2 by over a 1m units I'd imagine. DS will beat PS2 by 2m+ in December. So yeah, for hw, DS > PS2 by the end of 2010 in the USA.
