I would say that market saturation is really reached in one aspect. I guess there are almost no gamers left in japan that don't own a ds yet. That means that proven franchises won't be able to move hardware anymore, only casual titles that appeal to different groups than those titles that are already out will be able to move hardware significantly.
But anyways, the DS will keep selling about 100k units per week for at least another year and pass the PS2 easily.
