PS2 VS DS when will the DS catch the PS2 sales ?

[Mummelmann]

September 2010.

By the way; I'm sure I read last fall that there were nearly 140 million PS2's shipped as of september 1st 2009, with even more shipments does that mean there are 8-10 million PS2's sitting on shelves? I have a feeling that large chunks of sales from Eastern Europe and South America go unchecked, its especially big in parts of Eastern Europe.
