The DS keeps selling ~ 30 million a year.
It's looking at 28-30 million for 09
It sold 30.4 million in 08.
The Ps2 is down 40% YoY, and that's with a price cut. It has around 10 million left in sales, including the rest of the 09 sales.
At the end of this year, we can expect the Ps2 to be at 135M (+2.2 million) and the DS to be at around 124M (+13 million)
As the DS is pretty much selling 5m-5m-5m-15m in sales (That's Q1-Q2-Q3-Q4), I'd say that it should hit 138 million somewhere towards the end of Q3, or beginning of Q4 of 2010.
My guess would thus be September-October 2010.
The way I see it, DS is now at 170-200 million for lifetime sales. That is depending on when a new handheld is released, and assuming there won't be a 4th DS version.
