It was pretty clear by the middle of last year it peaked about February 2008 - Feb 2009. That said, there is also no evidence of a rapid decline and Sony only sold 30m PS2s at more than $200, Nintendo sold 55m Wiis at $250.
In the USA, Wii has had one price drop in 40 months, while PS2 was nearing its third price cut...and Wii is still ahead by ~6m (a year at the rate PS2 was selling in the USA)

Basically, because of how long Nintendo has managed to go without cutting price, the company can engage Sony / Microsoft in a nasty price war if necessary over the next year - two years. A 30 million base with every system sold at $200+ is historical for the USA market though, and it will happen in four to five months, tops.
