Those are amazingly sketchy numbers.
As for 2009,
Nintendo's average hardware sale price should actually increase this year with the launch of the DSi, while the other 4 systems could all potentially see price drops. Wii is the system which was the furthest from its software unit sales peak in 2008. DS should at least equal its software sales from 2008, and probably keep growing.
The only factors working against Nintendo making more huge marketshare strides are the potential drop in unit hardware sales of DS, and a potential drop in average software sale price.
"[Our former customers] are unable to find software which they WANT to play."
"The way to solve this problem lies in how to communicate what kind of games [they CAN play]."
Satoru Iwata, Nintendo President. Only slightly paraphrased.
